Abstract:
This study is concerned with the deformation field of the reinforced soil based on the consolidated drained triaxial test, using digital image processing technique in deformation measuring of soil specimen in trialxial test. In order to research the relation between anti-deforming capacity and strain of reinforced soil, intensity characteristic and failure mode, the glass fiber was used as a material of reinforce and 30 groups of triaxial tests were performed under 2 different reinforced positions and 3 types of confining stress. Together with digital image processing technique, we researched the transverse and vertical deformation ratios of reinforced soil in deformation process, drawn the deformation diagram of soil specimen in peaked strain and probed the reinforce mechanization and formation of shear field in reinforced soil. It was shown from the result that the geogrid has a great restraint, which increases with the growth of confining stress, on transverse deformation in medium sand. However, in final, the geogrid is incapable of changing the breakdown trend of soil body.

Abstract:
Changing a layer of weak soil in deformed foundation with a compacted soil bed consisted of various strong materials (sand, gravel, pebble-gravel, production waste materials). Existing calculation methods and techniques to build compacted soil beds based on weak highly compressive soils do not meet up-to-date requirements. Calculation methods used the dimensions of compacted beds quite often appear to be overestimated, and this results in increase in costs and working hours needed to build artificial foundation. The paper presents the possibility of using reinforced soil beds as an efficient method to build artificial foundation based on weak soils.

Abstract:
AbstractLarge quantities of waste tires are released to the environment in an undesirable way. The potential use of this waste material in geotechnical applications can contribute to reducing the tire disposal problem and to improve strength and deformation characteristics of soils. This paper presents a laboratory study on the effect of granular rubber waste tire on the physical properties of a clayey soil. Compaction tests using standard effort and consolidated-drained triaxial tests were run on soil and mixtures. The results conveyed an improvement in the cohesion and the angle of internal friction the clayey soil-granular rubber mixture, depending on the level of confining stress. These mixtures can be used like backfill material in soil retaining walls replacing the clayey soil due to its better strength and shear behavior and low unit weight. A numerical simulation was conducted for geosynthetic reinforced soil wall using the clayey soil and mixture like backfill material to analyzing the influence in this structure.

Abstract:
Reinforced soil-retaining structures that have been working in near-water environments for a long time are likely to affect their own mechanical properties due to the dry-wet cycle caused by changes in water level. In response to this problem, this paper uses a combination of macro- and microtests, selecting reinforced soil samples with four water content conditions, five overburden pressure conditions, three sets of dry-wet cycle conditions, and a total of 60 working conditions for testing. Scanning electron microscopy was used to observe the microscopic characterization of the reinforced soil particles under different times of the dry-wet cycle, and the pull-out test was used to study the mechanical properties of the interface of the reinforced materials and soils. The analysis results of the test show that the dry-wet cycles increase the porosity of the reinforced soil and the number of pores, among which the proportion of micro and small pores increases, the abundance and fractal dimension of reinforced soil particles increase, and the roughness of the particle surface is reduced. The change of the microstructure of the reinforced soil causes the cohesion of the soil to decrease in the macroscopic view. The friction coefficient and the ultimate pull-out force of the interface between the reinforced materials and the soils decrease with the increase of times of dry-wet cycle.

Abstract:
Cement is commonly used in the rapid construction of emergency airports; however, cemented soils have issues with integrity and crack resistance. For example, cemented soils can crack easily, and overall stability is insufficient. To address these problems, cemented soil is reinforced with hybrid polypropylene fiber, and the anti-flying property, anti-wear property, and crack resistance of polypropylene fiber reinforced cemented soil with varying fiber lengths, fiber contents, and fiber combinations are examined through flying tests, wear tests, and crack tests. Results show that the reinforcement of fiber can significantly improve the anti-flying property, anti-wear property, and crack resistance of cemented soil. The content and fiber length have a great impact on properties of fiber reinforced cemented soil. The ideal length and content of fine polypropylene fiber are 12 mm and 0.3%, respectively. The ideal combination of hybrid polypropylene fiber reinforced cemented soil is 0.3% coarse polypropylene fiber with the length of 38 mm and 0.3% fine polypropylene fiber with the length of 12 mm. In addition, hybrid polypropylene fiber reinforced cemented soil mechanical properties exceed those of single polypropylene fiber reinforced cemented soil.

Abstract:
Slope failure triggered by soil erosion under rainfall remains one of the most difficult problems in geotechnical engineering. Slope protection with planting vegetation can be used to reinforce the soil and stabilize the slope, but the early collapse of the planting soil before the complete growth of plants becomes a major issue for this method. This paper has proposed a composite soil treatment and slope protection method using the geocell structures and the wheat straw reinforcement. The geocell structures improve the stability of the planting soil and provide a stable and fixed environment for the vegetation, while the wheat straw reinforces the soil and also increases the fertility. The authors have performed a total of 9 experiments in this work that are classified into three groups, i.e., the unsupported slopes, the geocell reinforced, and the geocell and wheat straw composite reinforced with a consideration of three different rainfall intensities. The progressive slope failure development during the rainfall was assessed, as well as the soil erosion, the slope displacement, and the water content. The results show that the slope failure increases as the rainfall continues, and the soil degradation increases with the intensity of rainfall. The soil treatment using geocell improves the slope stability, but the geocell and wheat straw composite reinforcement has the best erosion control and slope protection.

Abstract:
In this study a limit equilibrium method is proposed to determine the bearing capacity of strip foundations on geosynthetic reinforced sand soils. A two-layered granular soil was foreseen to represent the loose in situ soil and the compacted fill above the reinforcement. First the modified bearing capacity factors Nq and Nγ were derived for the two layered granular reinforced soil. The bearing capacities were also calculated for different reinforcement geometries and soil properties using Finite Element analyses. The bearing capacities obtained from Finite Element and Limit Equilibrium analyses were compared, it was seen a good agreement. Therefore, it was concluded that the new limit equilibrium method proposed in this paper for reinforced two-layered soils can be successfully used in calculating the bearing capacities of geosynthetic reinforced soils.

Abstract:
As one of complex body, the strength of reinforced lime-soil with wheat straw was influenced by many factors. In order to gain quantitative contributed proportion, traxial compression tests of reinforced lime-soil, which took some factors like reinforced length, reinforced ratio and consolidation in account, were carried out by orthogonal design, and then evaluated by methods of range analysis and principal component analysis. Results are as follows. (1) Contributed proportion of consolidation is the highest, while, successively, of reinforce ratio and of reinforced length. Consolidation has the positive contribution to cohesion which the correlation coefficient can be up to 0.81, however, reinforced ratio takes negative contribution and the correlation coefficient is (-0.71). (2) The optimal reinforced condition of wheat straw is 20 mm in length and 0.25% in ratio as to the sample diameter of 61.8mm. (3) Results of principal component analysis and range analysis are both corresponded with that of experiment. These two kinds of statistics analysis methods are suitable in the domain of reinforced soil.

Abstract:
An extensive literature review was conducted to collect and synthesize information on geosynthetic-reinforced soil (GRS) walls that had been monitored for extended periods of time for assessment of their long-term performance characteristics. As a result, seven GRS retaining wall projects were selected. These projects typically had well-documented, longterm reinforcement strain data, wall deformation data, and design information. The walls range from 4.5 m to over 12 m in height and typically include surcharge loads composed of earth fills or traffic loads. Reinforcement materials were polypropylene and polyester geogrids or geotextiles, ranging in short-term strength from 5.8 kN/m to more than 17 kN/m. The facings used on the walls were concrete modular blocks, concrete panels, or wrapped geotextile surfaces. Some of the walls were constructed on poor foundations, whereas others were constructed on competent foundation materials. The environmental conditions vary from freezing temperatures in Ontario, Canada, to temperatures up to 44°C for walls built in the state of Arizona. The measured performance data for the seven GRS walls were evaluated in detail. The results indicate that creep deformation was very small when well-compacted granular backfill was employed and that current design methods are overly conservative regarding long-term creep of geosynthetic reinforcement in the GRS walls. A rational procedure for predicting long-term creep deformation of GRS walls is proposed that involves conducting a soil-geosynthetic interactive performance test with on-site soil and the use of a long-term creep equation developed on the basis of the behavior of the seven GRS walls.

Abstract:
The modern forms of reinforced soil walls were introduced by Henri Vidal. Since then design theories have been developed alongside an increasing database of full scale, small scale and centrifuge model tests. However, very little data is available on the mechanisms of deformation for a wrap-around wall. In order to understand these mechanisms, reinforced soil walls were tested under different conditions, by varying reinforcement stiffness, backfill material, external loading and type of construction. Seven centrifuge model tests on reinforced soil models were carried out with three different types of model reinforcements and a choice of two granular backfill materials. The external loading was imposed by a strip surcharge of 100 kPa, to represent the worst load experienced on a highway or railroad. This research programme includes the development of testing methods to obtain stress-strain behaviour of the model reinforcement using fixed or roller clamps, and improvement of the construction of the Cambridge strip load cells for measuring the tension along the model geosynthetic reinforcement, and in particular to the most sensitive, weakest reinforcement. Strip load cells have successfully yielded experimental data of reinforcement tension for all the geomaterials used. The tension measurement along the reinforcement confirms that the facing of a geosynthetic wrap-around reinforced soil wall does not serve a major structural function. Boundary relaxation occurs requiring the reinforcement simply to retain the fill. The deformation of the reinforced soil walls was identified by a simple displacement mechanism which included constant shear strain and dilation in the deforming zone. A non-dimensional horizontal deflection chart was derived based on this assumption. The prediction of the front wall deformation of centrifuge model walls using such a non-dimensional chart indicated that this would offer a useful serviceability design method to designers.

A utilização de pneus usados é uma técnica interessante para reforço de solos, sob o aspecto ambiental. Os pneus usados constituem uma matéria-prima abundante e de custo reduzido. A técnica de utilização de pneus em obras geotécnicas vem sendo difundida no Brasil desde meados dos anos 90, com a construção do muro experimental de solopneus da PUC-Rio, em colaboração com a Fundação Geo-Rio e a Universidade de Ottawa (Canadá). O presente trabalho tem por objetivo apresentar a metodologia para avaliação da resistência ao arrancamento de malhas de pneus. Os pneus podem ser dispostos em um plano horizontal e amarrados entre si, formando uma malha de reforço. Podem ser utilizados pneus inteiros ou com uma das bandas laterais cortadas. A sobrecarga atuando no reforço provém do confinamento provocado pela altura do aterro de solo, construído sobre a malha de pneus. Os ensaios de arrancamento dos pneus no campo utilizaram uma estrutura metálica de reação, atirantada, a qual foi desenvolvida especificamente para o programa experimental sobre reforço de solos. Os resultados permitiram idealizar um mecanismo de ruptura envolvido no processo de arrancamento das malhas de pneus, bem como a verificação das características de resistência e deformabilidade deste tipo de reforço.
The use of scrap tires as soil reinforcement is an environmentally interesting technique. Scrap tires are an abundant and low cost waste material. The technique for using tires in geotechnical construction is becoming popular in Brazil since the construction of an experimental gravity wall made with soil and tires in 1995. This wall was part of a research project by carried out by PUC-Rio in collaboration with Geo-Rio and University of Ottawa. The objective of this work is to present a methodology to evaluate the pull-out behaviour of tire meshes. The tires can be placed in a horizontal plane and tied with rope or wire, forming a reinforcement mesh. The surcharge on these meshes comes from the confinement due to the height of a soil embankment built on the mesh. Field pull-out tests were performed on these reinforcement meshes, using a metallic reaction structure, which was developed specifically for this experimental research. The results allowed the idealization of a shearing mechanism based on the pull-out of tire meshes, as well as the verification of the strength and deformability characteristics of the reinforcement.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
A utilização de materiais geossintéticos como reforço em obras geotécnicas vem crescendo bastante nas últimas décadas. A geogrelha, cuja função primária é o reforço de solos, é um entre os diversos tipos de geossintéticos, que vêm sendo utilizados. Diversas são as formas de interação da geogrelha com o solo em um maciço reforçado e o entendimento dos mecanismos que se desenvolvem nestas interações é essencial, pois só a partir daí pode-se obter parâmetros confiáveis para projeto. Pesquisas vêm sendo realizadas por diversos autores, mas muitos aspectos ainda devem ser estudados para que se tenha uma melhor compreensão do comportamento de solos reforçados com geogrelhas. A utilização de uma ferramenta numérica pode ser uma alternativa para que consigamos dar um passo adiante no entendimento da técnica de solo reforçado. Então, modelagens numéricas de ensaios triaxiais e de cisalhamento direto em solos reforçados e não reforçados foram realizadas com a utilização do programa Plaxis. Foram analisadas a influência do reforço no aumento da rigidez e resistência do solo e a resistência de interface solo-reforço. Para calibrar o programa e validar as análises numéricas, foram realizadas retro-análises dos ensaios realizados por Sieira (2003), onde se definiram aspectos importantes para modelar os ensaios, tal como, a melhor forma de impor as condições de contorno. Os resultados obtidos nas análises numéricas dos ensaios triaxiais sugerem que o programa Plaxis permite de forma razoável a reprodução dos ensaios reforçados, sendo possível prever o ganho de resistência do solo com a inclusão do reforço. Uma análise alternativa, onde se aplica um incremento de tensão confinante representativo da influência do reforço, foi também realizada. As análises numéricas dos ensaios de cisalhamento direto em solo arenoso não reforçado permitiram verificar a rotação do eixo das direções das tensões principais quando é aplicado carregamento cisalhante e a presença de uma zona central de cisalhamento (zona de cisalhamento). A resistência de interface sologeogrelha não foi bem reproduzida, indicando que o Plaxis não permite este tipo de avaliação. Quando os reforços encontravam-se inclinados, verificou-se a maior eficiência do reforço rígido e fazendo ângulo de 60º com a superfície de ruptura.
The use of geosynthetic materials as reinforcement in geotechnical engineering works is significantly increasing over the past decades. Geogrid, whose primary functions is reinforcing the soil mass, is one of the geosynthetics that has been used. In a reinforced soil structure, there are different types of interaction between soil and geogrid. To be possible to obtain reliable design parameters is essential to know the mobilized mechanisms in the interaction. This situation has been investigated by many researchers, but there are still many aspects to be better understood about geogrid reinforced soil behavior. In this research, numerical tools have been used to improve our knowledge about reinforced soil techniques. Numerical modeling of triaxial and direct shear tests on reinforced and non reinforced soils were carried out using software Plaxis. It was verified the resistance and stiffness increase of the soil due to geogrid inclusion and the interface soil-reinforcement resistance parameters. To calibrate the software and to validate the numerical analyses, back-analyses of the tests carried out by Sieira (2003) were done. These results helped to define important aspects to the tests modeling such as geometry and tests boundary conditions. The numerical analyses of the triaxial tests suggest that the software Plaxis reasonably allow an adequate reproduction of the reinforced soil tests. It was possible to foresee the increase of soil resistance because of reinforcement inclusion. In addition, an alternative analysis, where one applies a confining stress that reproduces the reinforcement influence, it was done. Numerical analyses of non reinforced direct shear tests had numerically evidenced the rotation of the axis of the principal stresses directions and the presence of a central zone of shear (shear zone). The soil- geogrid interface resistance was not well reproduced, indicating that Plaxis does not allow this type of evaluation. To inclined reinforcement relative to failure plane, it was verified the maximum gain of resistance is achieved with inclined reinforcement at 60º and when rigid geogrids are used.

Abstract:
Soil based construction materials (SBCMs) are formed of a mixture of gravel, sand and clay which, when mixed with water, may be used for construction. They can be an environmentally-friendly alternative to more traditional construction materials such as concrete and fired brick. SBCMs commonly incorporate foreign material into the soil to enhance the material properties. Many guides on SBCM construction advocate the use of cement as a stabiliser to strengthen the material, which detracts from the environmental credentials that earthen construction materials possess. Alternatives methods to strengthen SBCMs are therefore needed. In this thesis, waste wool fibres from a carpet manufacture are investigated as a potential alternative fibrous reinforcement in rammed earth (RE), and its effect on the behaviour of stabilised and unstabilised RE is assessed. Compressive tests, shear tests and splitting tests are performed to study the effect of fibrous (wool) and chemical (cement) stabilisation on RE, and recommendations on further use of these materials are made. Tests are also performed to investigate the shrinkage of different clays (bentonite and kaolinite) used in RE when mixed with sand or wool, in order to determine the effects of these materials on shrinkage behaviour. Finally, advice is provided regarding the use of fibrous reinforcement in SBCMs, which is applicable to both the SBCM industry and research, and new and pre-existing research areas are identified to prompt further study.

Abstract:
Fibres are mixed with soils to enhance their strength and hydraulic characteristics. Fibre-mixed soils are often known as the fibre-reinforced soils. In the past, both systematically and randomly reinforced soils have been used widely in civil and geotechnical structures. Randomly reinforced-soils using fibres exhibit advantages over systematically reinforced-soils because systematic reinforcements may result in weak planes within the soil mass. Randomly distributed reinforcements are also easier to apply and maintain for some applications. Previous researchers have studied the strength, compaction and compressibility behaviour of fibre-reinforced soil. Study on characteristics of fibre-reinforced soils when saturated, however, is limited to piping resistance improvement. One of the main reasons for collapse of some of the hydraulic structures is soil piping that takes place on the downstream side as a result of upward seepage. Fibre-reinforced soils can be a solution in sustainable watershed management as they can be used in irrigation and drainage projects, such as river levees, contour bunds, temporary canal diversion works, temporary check dams, soil structures, stream restoration, etc., for seepage and permeability control. This study focuses on permeability characteristics of fibre-reinforced soil. Permeability characteristics can vary depending on soil, fibre and methods used. Materials used in this study are Perth sandy soil, and locally available jute and waste tyre fibres. These materials were chosen because they are abundantly available in Perth area and surroundings. As for the waste tyre fibre, it was also chosen as a green approach to use waste materials in structures and solve their disposal problems. Fibre content varied from 0 to 10% with 1% intervals for tyre fibres and from 0 to 1.5% with 0.25% intervals for jute fibres. Fibre length varied from 5 to 25 mm with 5 mm intervals for jute fibres. Fibre length was constant in all experiments for tyre fibres as they come in a mixture of different lengths and studying the effect of length of permeability characteristics was not possible. Experimental tests were conducted on fibre-reinforced specimens in a constant-head permeameter. Experimental results suggest that the coefficient of permeability increases with an increase in fibre content for both fibre types (up to 100% for jute fibres and up to about 40% for tyre fibres). Also, it is observed that the coefficient of permeability increases with an increase in fibre length for jute fibres, as a general trend. As expected, water content increases and dry and saturated unit weights decrease with inclusion of higher fibre contents and longer fibres as a general trend. Fibre-reinforced soil specimens and the water discharge were modelled numerically using the commercial software SEEP/W in order to study the effects of fibre inclusion on permeability characteristics. The findings from the developed numerical model agree well with the experimental observations.

Abstract:
This technical report documents the second of a two-phase research and development (R&D) study in support of the development of a combined Load and Resistance Factor Design (LRFD) methodology that accommodates geotechnical as well as structural design limit states for design of the U.S. Army Corps of Engineers (USACE) reinforced concrete, hydraulic navigation structures. To this end, this R&D effort extends reliability procedures that have been developed for other non-USACE structural systems to encompass USACE hydraulic structures. Many of these reinforced concrete, hydraulic structures are founded on and/or retain earth or are buttressed by an earthen feature. Consequently, the design of many of these hydraulic structures involves significant soil structure interaction. Development of the required reliability and corresponding LRFD procedures has been lagging in the geotechnical topic area as compared to those for structural limit state considerations and have therefore been the focus of this second-phase R&D effort. Design of an example T-Wall hydraulic structure involves consideration of five geotechnical and structural limit states. New numerical procedures have been developed for precise multiple limit state reliability calculations and for complete LRFD analysis of this example T-Wall reinforced concrete, hydraulic structure.

Abstract:
This technical report documents the research and development (R&D) study in support of the development of a combined Load and Resistance Factor Design (LRFD) methodology that accommodates both geotechnical and structural design limit states for design of the US Army Corps of Engineers (USACE) batter pile-founded, reinforced concrete flood walls. Development of the required reliability and corresponding LRFD procedures has been progressing slowly in the geotechnical topic area as compared to those for structural limit state considerations, and therefore this has been the focus of this first-phase R&D effort. This R&D effort extends reliability procedures developed for other non-USACE structural systems, primarily bridges and buildings, for use in the design of batter pile-founded USACE flood walls. Because the foundation system includes batter piles under flood loading, the design procedure involves frame analysis with significant soil structure interaction. Three example batter pile-founded T-Wall flood structures on three different rivers have been examined considering 10 geotechnical and structural limit states. Numerical procedures have been extended to develop precise multiple limit state Reliability calculations and for complete LRFD analysis of the example batter pile-founded, T-Wall reinforced concrete, flood walls.

Full text
Abstract:
The design of buried pipes, in terms of the allowable minimum and maximum cover heights, requires the use of both geotechnical and structural design procedures. The geotechnical procedure focuses on estimating the load on the pipe and the compressibility of the foundation soil. The focus of the structural design is choosing the correct cross-section details of the pipe under consideration. The uncertainties of the input parameters and installation procedures are significant. Because of that, the Load Resistance Factor Design (LRFD) method is considered to be suitable for the design of buried pipes. Furthermore, the interaction between the pipe structure and surrounding soil is better captured by implementing soil-structure interaction in a finite element numerical solution technique. The minimum cover height is highly dependent on the anticipated traffic load, whereas the maximum cover height is controlled by the section properties of the pipe and the installation type. The project focuses on the determination of the maximum cover heights for lock-seam CSP, HDPE, PVC, polypropylene, spiral bound steel, aluminum alloy, steel pipe lock seam and riveted, steel pipe and aluminum arch lock seam and riveted, non-reinforced concrete, ribbed and smooth wall polyethylene, smooth wall PVC, vitrified clay, structural plate steel or aluminum alloy pipe, and structural plate pipe arch steel, or aluminum alloy pipes. The calculations are done with the software CANDE, a 2D plane strain FEM code that is well-accepted for designing and analyzing buried pipes, that employs the LRFD method. Plane strain and beam elements are used for the soil and pipe, respectively, while interface elements are placed at the contact between the pipe and the surrounding soil. The Duncan-Selig model is employed for the soil, while the pipe is assumed to be elastic. Results of the numerical simulations for the maximum fill for each type and size of pipe are included in the form of tables and figures.

Garcia, Lyan, James Rowland, and Jeb Tingle. Evaluation of geocell-reinforced backfill for airfield pavement repair. Engineer Research and Development Center (U.S.), December 2021. http://dx.doi.org/10.21079/11681/42550.

Full text
Abstract:
After an airfield has been attacked, temporary airfield pavement repairs should be accomplished quickly to restore flight operations. Often, the repairs are made with inadequate materials and insufficient manpower due to limited available resources. Legacy airfield damage repair (ADR) methods for repairing bomb damage consist of using bomb damage debris to fill the crater, followed by placement of crushed stone or rapid-setting flowable fill backfill with a foreign object debris (FOD) cover. While these backfill methods have provided successful results, they are heavily dependent on specific material and equipment resources that are not always readily available. Under emergency conditions, it is desirable to reduce the logistical burden while providing a suitable repair, especially in areas with weak subgrades. Geocells are cellular confinement systems of interconnected cells that can be used to reinforce geotechnical materials. The primary benefit of geocells is that lower quality backfill materials can be used instead of crushed stone to provide a temporary repair. This report summarizes a series of laboratory and field experiments performed to evaluate different geocell materials and geometries in combinations with a variety of soils to verify their effectiveness at supporting heavy aircraft loads. Results provide specific recommendations for using geocell technology for backfill reinforcement for emergency airfield repairs.
