Full textAbstract:
Between 1881 and 1894 the Boston & Albany Railroad undertook a major program of capital investment and improvements to the physical facilities of the line, including the construction of over 30 new passenger stations. H. H. Richardson's close friends, James A. Rumrill and Charles S. Sargent, as the two members of the B&A Board most interested in construction, were given responsibility for this program. They directed the commissions to Richardson and after his death to his successors, Shepley, Rutan and Coolidge. Richardson's nine B&A station designs were generally variations on a simple theme-small rectangular stone blocks with overhanging roofs providing sheltered waiting space at trackside. The continuation of this approach by Shepley, Rutan and Coolidge in 23 additional station designs resulted in a remarkable consistency of character and quality throughout the B&A system. This consistency was also fostered by the continuing participation of Norcross Brothers of Worcester (Richardson's "Master Builder") as contractor, and by the participation of F. L. Olmsted, whose design of landscaped settings for many of the stations contributed to the establishment of the B&A program of "railroad gardening." While the stations were small commissions, the totality of the B&A program represents an impressive collaboration of designer, contractor, and client which has seldom been equalled.

Objective: The study of railroad transport rate-setting system from a position of customer-oriented approach and logistics, particularly the development of specific practical proposals of freight delivery system optimization and the assessment of OJSC “Russian Railways” logistic (terminal stocking) activity indices. Methods: Analytical method was applied, as well as economical and mathematical tools of terminalistics, being a new school. Results: An attempt was made to review the existing railway freight delivery system. It was observed that it was unreasonable to exclude materials handling elements - logistical objects (LO) of different types, from a logistical chain as by means of the element in question the freight arrives at as well as leaves the railroad. If the focus is made only on operating indices of functioning and traffic section of a logistical chain, it artificially impoverishes the strongest functional of railway enterprises, leading to a simplistic approach of traffic process managing and does not contribute to freight flow transferring to railroads. A new system of indicators was suggested for economic justification and calculation of parameters LO and TS, which were missing before. All indices were adjusted to the existing system of economical and operational indices of storage yard and railroads functioning. The new system may be applied in logistical rating, as well as terminal and stocking infrastructure of OJSC “Russian Railroads”. It may be used for: 1) LO identification; 2) LO selection taking into account its functionality, dislocation, etc. ; 3) construction projects’ assessment and reconstruction of terminal and stocking railroads’ infrastructure facilities; 4) logistical functioning of OJSC “Russian Railroads” holding company; 5) LO construction; 6) railroad transport functioning forecasting and planning. Practical importance: The application of the originally developed system of indicators will allow OJSC “Russian Railroads” to effectively design, operate and plan the functioning of terminal and stocking infrastructure facilities. The effectiveness of the suggested TSS is in more rapid freight delivery to consumers, expenditure reduction in technical maintenance and ineffective railway sidings and section’s stations repair, shunting and exporting train locomotives release, as well as passing siding of a section’s station for more effective formation of exit routes, technical and station’s speed increase of line haul main directions through home-base station, due to a number of train operation paths release, occupied with demountable export trains’ operation.

Rail is a construction in one unit made of steel, concrete, and other construction materials above or below the ground depending on the direction and area. The condition of the rail surface must not have any defects so that train travel is safe and comfortable. This research method discusses the research design. There are four processes in this research design, namely the data acquisition process, the RGB image color conversion process to HSI, the filtering process using the gabor filter, and the classification process using deep learning neural networks. The purpose of this study is to build a system to visually detect defects in the surface of the railroad tracks, namely image processing techniques. This activity was carried out at the Madiun Indonesian Railways Polytechnic Station Laboratory. Based on the research that has been done, it can be concluded that an image with a size of 32x32 pixels produces the highest accuracy value at epoch 90 using the gabor filter image type. The more epochs used, the better the results will be and the better the model can be made. The accuracy results obtained were 0.8041 or 80.41% for training accuracy and testing accuracy of 0.79 or 79%

The Central Artery/Third Harbor Tunnel Project in Boston, Massachusetts, is one of the largest highway projects over undertaken in the country. It requires the replacement of the existing elevated artery, I-93, with an underground tunnel extending through downtown Boston and an extension of the Massachusetts Turnpike Authority (MTA) I-90 from its existing termination at the I-93 interchange to Boston's Logan International Airport. The I-90 extension tunnels east under the existing South Station intercity and commuter railroad tracks, under historic Fort Point Channel while crossing above the 1915 twin subway tunnels, and continues through industrial South Boston with ramps surfacing in a new South Boston interchange, the heart of tremendous growth in Boston. From there the tunnel connects to the recently completed Ted Williams Tunnel harbor crossing to East Boston and Logan International Airport. The unique design challenges and solutions relating to the Fort Point Channel crossing, particularly the use of in-the-wet construction with concrete immersed-tube tunnels and the design interface to the ventilation structures, are presented. Structures required for the I-90 extension are concrete immersed tubes and jacked tunnels, as well as more conventional cut-and-cover tunnels, bridges, surface roads, and ancillary buildings. The geometric and physical restraints of the alignment initially required the placement of the ventilation building, which serves the tunnels, on a cut-and-cover tunnel transition section between the jacked tunnels and the concrete immersed tubes. Ultimately, placement of the ventilation building on the immersed tubes created a substantial cost and schedule benefit.

Full textAbstract:
On the basis of a wide range of sources, the research analyzes the history of the study of permafrost in the territory of the European Northeast of Russia in the first half of the 20th century. The documentary sources revealed in the Archive of the Russian Academy of Sciences (Moscow), the National Archive of the Komi Republic (Syktyvkar), the Scientific Archive of the Komi Science Center of the Ural Branch of the Russian Academy of Sciences (Syktyvkar), the Vorkuta Museum and Exhibition Center (Vorkuta) are introduced into the scientific use for the first time. The 1920s became the period of the birth of a new scientific direction – permafrostology. This science gave an impetus to the systematic study and development of the North and the Arctic. The beginning of systematic geocryologic studies was connected with the development of the European Northeast in the 1920s–1930s. It has been determined that the USSR Academy of Sciences played the leading role in carrying out these studies: it organized special scientific expeditions for studying the cryolithozone of this region. The main results of the studies and their motives interconnected with the government’s interests in the development of valuable northern mineral resources are shown. The results of the expeditions were conclusions about the possibility of constructing large industrial facilities in the regions of the explored reserves of natural raw material resources. Following scientists’ recommendation, the industrial development of the Pechora coal basin and the colonization of the polar region began. The climatic and natural features of the region demanded stationary scientific research in the field of design and construction. The Vorkuta Research Permafrost Station (VRPS) (1936–1958), created under the supervision of the USSR Academy of Sciences, began to carry out this research. Today, the history of this station’s activities is poorly studied. The article presents the main directions of VRPS research: engineering permafrostology and general issues of permafrost studies. The staff of the station were researchers of the Committee on Permafrost Studies of the USSR Academy of Sciences and scientists from among prisoners of GULAG. The role of the staff who made a great contribution to permafrost studies is shown. Under the leadership of the scientists of the station, on the basis of their techniques, large industrial structures of Vorkuta District and Vorkuta, among them the first railroad in the conditions of permafrost, were designed. The conclusion is drawn on the leading role of scientists of the USSR Academy of Sciences in carrying out studies of permafrost soil in the European Northeast in the first half of the 20th century which became the basis in the successful solution of construction problems in the Arctic territory.

Objective: Further improvement of organizational management methods for construction and renovation of railroad stations by the example of marshalling complexes infrastructure. Methods: By means of the methods of continuous construction theory, depending on technological arrangement and structure of facilities of railroad stations, an optimum amount of work was singled out for the purpose of construction lines development. Effective variants of organizational management were selected according to rational coefficient values of combining the facility and specialized flows, in case of which the maximum possible (for conditions of construction and renovation) estimated capacity of the station was preserved. Results: The dependencies of estimated capacity and the amount of work for construction and renovation of marshalling complexes of different types (one-way, combined, etc.) were determined. Practical importance: The data presented in the article is of high practical relevance due to the absence of modern research and industrial regulatory documents on construction and renovation management of the given type of transport facilities.

This paper presents and analyses the redefined Rijeka railway junction. The redefined concept of the Rijeka railroad hub in the context of port and railway interdependence dictates the need to find the accommodation of cargo transport to peripheral locations such as: Krasica, Kukuljanovo, Bakar, Ivani, Bršica and capacity for the island of Krk, while passenger transport would be implemented in the urban area. The most important projects related to Rijeka rail transport system are the construction of a new line of high efficiency between Zagreb and Rijeka, and a new railroad through the tunnel of Učka which will link the ports of Rijeka, Koper and Trieste. Together with the reconstruction of cargo stations Rijeka and Brajdica, an extension of the other tracks on the railroads Škrljevo-Rijeka and Rijeka-Opatija/Matulji should be performed as well as the construction of Krasica, Ivani, Tijani and Vrgljevo stations. The construction includes a multipurpose bridge to the Island of Krk and a railway line to the new container terminal as well as the new railway bypass to “elevation 200”. KEY WORDS: Rijeka railway junction, railway transport system, railway transport, Port of Rijeka

Railroad transportation system is considered a viable model in several aspects; however, its implementation is dependent on several decision factors, which include regional production viabilities, specific locations for railroad station construction, land slope, among others. This work aims to indicate the optimal location for new railroad stations and the best interconnection path among them in order to expand the railroad network of the Paraná State (Brazil) to regions that are not contemplated by this type of transportation. The layers used as information plans contemplated the geographic location of the regions with the highest representativeness in the agroindustrial production, associated with the demands and transportation of production and topographic relief. Was defined 1,390.802 km of new railroads, mainly in the Western and Southern Center regions of Paraná. This implantation generates a very significant importance for the municipalities since it increases the demand of revenues and generation of new currencies.

Full textAbstract:
In railroad construction—in particular, direct-fixation tracks—a longitudinal concrete block known as a “plinth” is used to elevate the profiles of the railroad track from the aerial guideway (e.g., bridge deck). A post-construction alignment revision is often required if the plinth elevation surpasses its maximum tolerance after the concrete pour. In such cases, the plinth surface needs to be grinded to meet the design elevation, or a shim should be inserted underneath the rail pad to raise the profile elevation. Considering both sides of the rail plinths, vertical design factors, and performance specifications, re-optimization of the vertical profile is of great interest, but the process poses challenges and represents a practical research problem. An optimization model aimed at minimizing the cost of post-construction alignment repairs is proposed and a real-case numerical example is analyzed to check the effectiveness of the model.

Full textAbstract:
The Train Design Optimization Problem regards making optimal decisions on the number and movement of locomotives and crews through a railway network, so as to satisfy requested pick-up and delivery of car blocks at stations. In a mathematical programming formulation, the objective function to minimize is composed of the costs associated with the movement of locomotives and cars, the loading/unloading operations, the number of locomotives, and the crews’ return to their departure stations. The constraints include upper bounds for number of car blocks per locomotive, number of car block swaps, and number of locomotives passing through railroad segments. We propose here a heuristic method to solve this highly combinatorial problem in two steps. The first one finds an initial, feasible solution by means of an ad hoc algorithm. The second step uses the simulated annealing concept to improve the initial solution, followed by a procedure aiming to further reduce the number of needed locomotives. We show that our results are competitive with those found in the literature.

Purpose Railroad transit infrastructures are amongst major capital-intensive projects worldwide, which impose significant risks to the contractors of build-operate-transfer projects because of the fluctuations in steel price fluctuation. The purpose of this paper is to introduce a methodology for hedging steel price risk using financial derivatives. Design/methodology/approach Cox–Ross valuation lattice has been used as an option valuation model for determining option’s price for the construction companies involved in fixed-price railroad projects. A sensitivity analysis has been conducted using the financial option Greeks to evaluate the impacts of option’s pricing factors in the total price of option. Findings The result of valuation shows that European options cost to safeguard against the effects of price risk is only a fraction in contrast to the total cost of steel procurement for a typical railroad construction company. This confirms that using this kind of financial derivative is a beneficial yet effective approach for hedging steel price risk for railroad construction companies. Practical implications The applicability of the financial derivatives, both exchange-traded and over-the-counter instruments, is evident in broad financial industry. This paper shows how European options can be readily used for risk management of a typical railroad project, and explains the methodology in a step-by-step procedure. Originality/value Although the financial engineering literature is rife of theory and application of derivatives in various contexts, to the best knowledge of authors there is only few papers on the application of these well-developed financial instruments for risk management in construction industry. This study intends to illustrate how financial derivatives can add value to risky construction projects and shed new light in this important application area.

Full textAbstract:
Christian Chevandier's Cheminots en Greve is a social, political, and institutional history of railroad workers in France from 1848 to 2001. It is told from the standpoint of the role of strikes in forming the occupational identity of these workers, known in France as cheminots (Chevandier finds the earliest use of the expression dating back to 1898; by the 1930s the Academie Francaise officially recognized it as a French word). Cheminots belong to various crafts and trades. They drive the trains, repair locomotives and rolling stock in shops and factories, sell tickets in stations and collect them in trains. Although the book is largely structured around a chronological account of railway strikes, Chevandier looks beyond the strike for sources of cheminot identity. These include the evolving structure of the French railroad system from private companies to state ownership, the role of skill and technological change, and especially union strategies, structures, and above all divisions. Along the way he revisits earlier treatments of French labor and railworker history, and takes up old historiographical controversies debating, confirming, and refuting well-known scholars from Annie Kriegel to historians of a younger generation like George Ribeill and Atsushi Fukasawa.

As one kind of railroad tracks, the slab track already widely applied in the high-speed railroad. In order to satisfy the very high-speed-railroad security and the comfortable need, the request of slab track's ultimate subsidence is very strict during construction and operation. Examined in this paper is the roadbed subsidence rule of Wuhan – Guangzhou railway passenger special line in China. The site observation of roadbed subsidence deformation is utilized and has drawn up the settling curve. Goes a step further, based on the numerical calculus method and the forecast assessment, the roadbed subsidence rule of different ground reinforcement processing has been represented. It is shown that the ultimate subsidence satisfied the request of design and the subsidence deformation of CFG pile compound ground was smaller than that of other ground. These conclusions provide uses for reference importantly to guarantee the quality of slab track on railway passenger special line under construction.

The Railway Troops of the Armed Forces of the Russian Federation are intended for technical cover, restoration, demining and barrage of sections (objects) of the RF railroad transport infrastructure in the RF Armed Forces responsibility zone, increasing its survivability and carrying capacity, as well as planning the guidance and operation of floating railway bridges. The railway infrastructure is understood as "a technological complex, which includes subsystems of railway infrastructure, components of subsystems and elements of components of subsystems of railway infrastructure, ensuring the functioning of this complex" [1]. The tasks of the troops include the operation of existing and construction of new sections of railways, bypassing railway (railway) junctions, the construction of temporary railway bridges in order to ensure the actions of troops [2]. When restoring infrastructure facilities for railroad transport, the organization of work management and the promptness of restoring interrupted train traffic play a decisive role, which largely depends on the preparation and decision-making that requires certain engineering calculations. In particular, the development of design documentation for the construction of a bypass of a destroyed section of a road or a railway junction requires a significant amount of time. The most time-consuming document of design documentation is the calculation and construction of a longitudinal bypass profile. The article discusses the issues of automated construction of a longitudinal bypass profile, which can significantly reduce the time required for preparing design documentation, including for laying cable lines to restore the regulation of train traffic.

The Korean government has announced the construction of more than 310 hydrogen refueling stations by 2022 to establish a hydrogen infrastructure, which is crucial for realizing hydrogen economy. According to the fire act in Korea, most hydrogen refueling stations are not included in the specific structure for fire protection. Therefore, in this study, the fire protection facilities in hydrogen refueling stations and the amendment methods for those facilities were investigated using the Delphi method. A total of six fire protection facilities, including an automatic fire alarm system and sprinkler, were drawn. It is the conclusion of the paper, however the current fire act does not classified the hydrogen refueling station as the specific structure for fire protection. I think the following is better: Furthermore, hydrogen refueling stations needed to be included in the specific structure for fire protection by modifying the hydrogen storage tank volume. High-pressure gas act and relevant technical codes were further required to connect with fire regulations. Quantitative analysis of fire protection facilities and design codes for hydrogen refueling stations could provide information for the hydrogen infrastructure development.

Full textAbstract:
Purpose This paper aims to propose an automatic imaging network design to improve the efficiency and accuracy of automated construction progress monitoring. The proposed method will address two shortcomings of the previous studies, including the large number of captured images required and the incompleteness and inaccuracy of generated as-built models. Design/methodology/approach Using the proposed method, the number of required images is minimized in two stages. In the first stage, the manual photogrammetric network design is used to decrease the number of camera stations considering proper constraints. Then the image acquisition is done and the captured images are used to generate 3D points cloud model. In the second stage, a new software for automatic imaging network design is developed and used to cluster and select the optimal images automatically, using the existing dense points cloud model generated before, and the final optimum camera stations are determined. Therefore, the automated progress monitoring can be done by imaging at the selected camera stations to produce periodic progress reports. Findings The achieved results show that using the proposed manual and automatic imaging network design methods, the number of required images is decreased by 65 and 75 per cent, respectively. Moreover, the accuracy and completeness of points cloud reconstruction is improved and the quantity of performed work is determined with the accuracy, which is close to 100 per cent. Practical implications It is believed that the proposed method may present a novel and robust tool for automated progress monitoring using unmanned aerial vehicles and based on photogrammetry and computer vision techniques. Using the proposed method, the number of required images is minimized, and the accuracy and completeness of points cloud reconstruction is improved. Originality/value To generate the points cloud reconstruction based on close-range photogrammetry principles, more than hundreds of images must be captured and processed, which is time-consuming and labor-intensive. There has been no previous study to reduce the large number of required captured images. Moreover, lack of images in some areas leads to an incomplete or inaccurate model. This research resolves the mentioned shortcomings.

Purpose Building information modeling (BIM) is a process of generating and managing building data during the building’s life cycle. To increase productivity in building design and construction, BIM uses three-dimensional (3D) real-time, dynamic building modeling software. Because of its versatile features, BIM use is on the rise and researchers are exploring its application in new disciplines. The purpose of this study is to map out how BIM is used in the construction industry, while identifying and highlighting the research gaps in the literature. Design/methodology/approach To investigate the status quo of knowledge about BIM, the authors conducted a comprehensive literature review. They applied and extended a methodology for reviewing BIM-related publications through a four-dimensional meta-analysis system and its categories, which has been partially adapted previously. Findings Majority of studies applying BIM for the construction phase of civil engineering projects were done within universities; none used BIM for the construction of intermediate railway stations. Practical implications To increase the construction efficiency of intermediate railway stations, applying the BIM concept for generation and management of station data should be considered for future research. Originality/value Furthermore, one of the main goals of this research paper is to explore the adoption of BIM in civil engineering construction projects, in particular the construction of intermediate railway stations.

Through a comprehensive evaluation of the spaces of 25 railway stations, where power-saving operations are being conducted due to an earthquake, the effects of various components of the space on users’ psychology were reviewed. For the platforms of railway stations, which are divided into ‘island platforms’ and ‘side platforms’ the ‘physical quantity measurement’ and ‘impression evaluation’ were assessed. When a simple power-saving method, such as partial lighting up is adopted, it has been shown that there is a negative effect on the users, both physically and psychologically. In particular, in the case of outdoor platforms, there is a concern that glare and anxiety due to contrast may increase; therefore, it is necessary to utilize the reflective surfaces effectively. Floor illuminance is fundamental to lighting design. However, some areas cannot be evaluated by floor illuminance alone. The difference in the results of the impression evaluation in five areas with floor illuminance around 50 lx was widely distributed, and it was found that the shape and material of the space affected the results. If platform screen doors are installed, a lighting method that can evenly illuminate the interior of the space is necessary. By reviewing each factor that determines the visual impression, it was revealed that the lighting location and lighting method were significantly affected.

The problems faced by subway stations in the construction process are more complex than those by overground buildings. Therefore, the construction risk for such structures is highly unpredictable and the risk management is difficult. Building information modeling (BIM) technology has strong visualization, simulation, and integration characteristics that make it conducive to the development of a risk early warning system for underground engineering. According to the functional requirements of risk early warning for subway stations, a risk early warning system based on a BIM real-time construction model is designed in this study for a subway station construction. The operation process of the risk early warning system is established through the grey prediction method to propose the operation method of the early warning system. The early warning system is applied to the Xiangjiang New Town Station of Changsha Metro Line 4 in China to verify its feasibility.

Fire protection is an essential public service but also one of the costliest ones. Considerable resources are devoted to fire protection including equipment, staff, training, and the facilities to house them. Fire stations, in particular, have a significant cost impact on state and municipal budgets. Fire stations are required in most local governments and like other municipal buildings are central to identity. To limit the cost of operating a fire station, municipalities have looked to more green building options. Green-rating systems such as the Leadership in Energy and Environmental Design (LEED) system have been used in the U.S. to assess green buildings. Thus, this paper aims to analyze 95 certified fire stations under the LEED-NC 2009 version (v3) that are located in the United States. A scorecard analysis (credits and points) of public data available serve as the foundation to describe the status of the green design and construction of these fire stations. The findings indicate that the points in the Material Resources (MR) category are achieved at the lowest rate compared to the other categories, on average 38% of 14 available points were earned. In addition, the points in the Energy and Atmosphere (EA) category are one of the lowest achievement rates, equal to 40.2%. The data also shows that 82% of LEED-certified fire stations belong to career or mostly career type, which are municipality fire departments funded by local governments. The significance of this study is to demonstrate the importance of both MR and EA categories for the design and construction phases of green fire stations.

Current maintenance practices consume significant time, cost, and manpower. Thus, a new technique for maintenance is required. Construction information technologies, including building information modeling (BIM), have recently been applied to the field to carry out systematic and productive planning, design, construction, and maintenance. Although BIM is increasingly being applied to new structures, its application to existing structures has been limited. To apply BIM to an existing structure, a three-dimensional (3D) model of the structure that accurately represents the as-is status should be constructed and each structural component should be specified manually. This study proposes a method that constructs a 3D model and specifies the structural component automatically using photographic data with a camera installed on an unmanned aerial vehicle. This procedure is referred to as semantic structure from motion because it constructs a 3D point cloud model together with semantic information. A validation test was carried out on a railroad bridge to validate the performance of the proposed system. The average precision, intersection over union, and BF scores were 80.87%, 66.66%, and 56.33%, respectively. The proposed method could improve the current scan-to-BIM procedure by generating the as-is 3D point cloud model by specifying the structural component automatically.

The Vancouver Advanced Light Rapid Transit (ALRT) System consists of 21.4 km (13.3 miles) of grade-separated guideway between the cities of Vancouver and New Westminster. Of the total length, 16.6 km (10.3 miles) are elevated, 1.3 km (0.8 miles) are in tunnel, and 3.5 km (2.2 miles) are at grade. There are 15 stations and a maintenance and vehicle storage facility. The system uses linear induction motor driven, light-weight driverless cars which are automatically controlled from the operations center located in the maintenance facility.The guideway beam concept was developed in concrete with the requirement that direct track fixation be used without a second pour. The beams are post-tensioned, following erection into two- and three-span continuous structures, encastre at the internal supports, with single pot bearings at the expansion ends.During construction the management for the project was provided by a joint project organization (JPO) consisting of the system contractor, Metro Canada Ltd., and the owner, B.C. Transit. The JPO was formed part way through the project to reduce duplication of effort and improve communication and coordination.Quality assurance for all materials and construction was critical to the successful completion and operation of the system. To ensure quality, the JPO instituted a detailed quality assurance (QA) and quality control (QC) program, implemented through the construction management team.Production of the precast guideway beams for the project was undertaken by two separate contractors. The initial contractor produced the beams for the 1 km prebuilt or demonstration phase, requiring 74 beams. The second contractor produced the remaining and major portion of the elevated guideway beams, for phase 2, amounting to an additional 1040 beams. Information obtained from phase 1, the prebuilt section, was used to modify the structural design, equipment requirements, and production and construction methods for phase 2.The cost of the transit system including 114 vehicles and all operation and control equipment was budgeted for a maximum expenditure of $854 million of which approximately $240 million was for civil works for the guideway, stations, and maintenance yard.Construction of the guideway began in August 1983 and was completed in December 1985. The guideway began operation January 1, 1986 on time and on budget. Key words: transit, automated, design, construction, guideway precast, concrete, quality assurance.

The creation of modern reclamation systems is accompanied by the emergence of new technical solutions, the complexity of the design of individual elements and, as a result, an increase in labor and money costs for their design, construction and subsequent operation. There are also requirements for reducing the construction time of these facilities, and improving the efficiency of agricultural production on reclaimed lands. The creation of modern reclamation systems needs to clarify the traditional methodological approaches to solving a number of problems. In reclamation construction, closed irrigation systems are becoming increasingly widespread, the main elements of which are: a stationary or mobile pumping station, a closed irrigation network and sprinkler equipment. The experience of operating modern closed irrigation systems has shown that due to changes in the operating modes of pumping stations and sprinkler equipment, sharp pressure fluctuations (hydraulic shocks) occur in pipelines during certain periods, which can lead to network destruction, failure of pipeline valves and pumps. Hydraulic engineering and reclamation facilities must meet certain requirements for reliability and environmental safety. First of all, this is achieved by protecting pipelines from an unacceptable increase in pressure that occurs during hydraulic shocks caused by changes in the operation of pumping units. Damage and accidents in the pressure systems of a closed irrigation network can also occur during transients that occur when pumping units are started up in accordance with the work schedule. The purpose of the work is to clarify the calculation justification, design and safe operation of closed irrigation systems with pumping stations.

Full textAbstract:
To design a more suitable scheme under different conditions so that subway stations can play their role better, this study investigated the construction elements of subway stations in residential areas. Metro stations in residential areas are generally located at the intersection of urban roads. As the “handover space” of the city, the construction principle should be based on people’s experience. As the core basis for traffic planning and future operation management, construction of subways in residential areas should take into consideration factors such as trip volume, distribution, and mode selection of residents, and be determined based on such mathematical models as the unit factor method, gravity model, and disaggregated analysis method. Station site selection is based on the point, line, and surface elements, and the importance of a station in the line network is judged by degree and betweenness centrality; the accessibility of the line network is determined by connectivity. In this study, the influencing factors of residential area subway station construction are divided into construction elements and site selection. Internal construction elements of stations include station entrances and exits, escalators, ticket machines, and transfer routes, and the conclusion of the mathematical model is used to select or give opinions about the internal construction elements of the subway. The point, line, and surface elements and the connection relationship between the subway and buses are used to determine the site selection of the subway. Furthermore, this paper discusses the three elements that affect the construction of the subway, comprehensively considers the functional requirements of the subway, and makes reasonable adjustments to each element. Finally, the requirements for the elements of the subway construction are determined.

Full textAbstract:
As the hydro-engineering projects are often featured with long construction period, great investment and many cooperative departments; moreover, they are usually seriously affected by natural resources, topography, geology and hydro-meteorological condition; it seems quite necessary to design a set of network monitoring system to store, simulate and analyze the historical hydrologic data and planning data. This paper first briefly analyzes the simulation design status of current network monitoring system for hydropower stations, then explores or analyzes the structure of network monitoring system for small and medium-scale hydropower stations and the detailed design programs, and finally it describes its application prospects so as to offer references for others.
