Résumé :
Waterproofing is one of the key problems of underground structures. Spray-on waterproofing membrane is a new system in tunnels with single shell linings. The conditions of the application of this system are analyzed in terms of the deformation and surface condition of the first layer of the shotcrete shell, water ingress and water pressure behind the waterproofing membrane. The results show that the applications of a spray-on waterproofing membrane in a tunnel is possible if the deformation of the shotcrete and water pressures behind the sprayed membrane is properly controlled, as well as the ingress water is piped or tightened with practical measures. Proposals of measures to meet the conditions are presented for the application of the spray-on waterproofing membrane in tunnels.

Résumé :
In waterproofing mountain tunnels, the tunnel joint is the weak link. To explore the waterproof failure mechanism of the tunnel joint waterstop belt and to propose an optimization method for the waterstop belt, this paper combines tests and numerical simulations, summarizes the waterproofing mechanism of the waterstop belt, establishes a finite element model of the waterstop belt considering bonding and extrusion, and studies the waterproofing ability and mechanical properties of the waterstop. The main conclusions are as follows: (1) The waterproofing capacity of the water stop belt depends on its surface contact pressure and bonding force. (2) Waterstop deformation will partially destroy the bonding between the waterstop and concrete, reducing the reliability of the waterproofing mechanism. (3) When the deformation of the waterstop belt reaches a certain degree, its stress value is too large to meet the requirements of its service life. (4) The design can be optimized from two aspects: the bond between the waterstop and concrete, and the size of the waterstop.

Résumé :
China is currently at an important stage of urbanization. In recent years, the number and scale of under-lake tunnels in southern cities of China are growing consistently, which brings opportunities and challenges in intelligent construction and operation maintenance. Due to the long length of the under-lake tunnel, the large volume of concrete to be cast, the complex environment of the buried section and the underground environment of the lake bottom, the hydration heat and stress crack have been the main challenges of the under-lake tunnel engineering in crack control and waterproofing aspect. Simultaneously, with the development of big data, intelligent construction, information technology, and other techniques, these techniques are gradually applied to the whole life cycle of tunnel engineering including survey, design, construction, operation, and maintenance. The construction of the lake tunnel project is setting off a new round of technological innovation. This paper systematically summarizes the technical breakthroughs and application of technologies such as intelligent construction and information technology in the construction of under-lake tunnels in China, and puts forward reasonable suggestions on the key technologies of intelligent construction and operation maintenance for urban under-lake tunnel engineering.

Leakage in tunnels can not only shorten the life of lining concrete, but also cause malfunctioning of the equipments and deteriorating of the environment inside. In cold areas, it can also create freezing roads or even formation of icicles, which increases the risk levels of driving and leads to traffic accidents. Therefore, leakage in tunnels has become a major problem in maintenance and management of tunnels. Leak free tunnels have long been a goal for engineers in designing, building, and maintaining tunnels. Traditionally, tunnels are built using steel rod and reinforcement plate method. Since it is very hard to make tunnels leak free by these methods, measures have to be taken after tunnels are built to fix this problem. However, these measures tend to be temporary and they usually fail after a few years. The progress of NATM (New Australia Tunneling Method) in recent years makes completely leak free tunnels possible. When NATM is applied, a waterproof film is inserted between shot concrete and lining concrete. This film can form a reliable waterproof layer and effectively prevent leakage. European is the pioneer in this field and has more than 20years of experiences. Japanese started to try this method about 10 years ago. Many related materials and methods are being developed in local market, and however, is lacking its related studies. This study is focused on the selection and application of the waterproof film using experimental methods to provide the material specifications and operation procedures of the application. For the structure of the waterproof film, 0.4mm thick composite epoxy backing by sediment of fiber cushion is most commonly used. However, this may not be the best choice judging from the differences in European, American, and Japanese standards. Therefore, this study is based on NATM tunnel waterproof technology to discuss about selecting the structure of the waterproof film and the problems in the tunnel construction. Material, construction and management standards for waterproof tunnels are defined. Important items in the tunnel design and construction are also provided. In addition to that, this study also includes closely related issues such as anti-cracking measures for lining concrete and drainage construction.

Résumé :
Marshall Space Flight Center has developed and demonstrated a measurement device for sensing and resolving the hydrodynamic loads on fluid machinery. The device — a derivative of the six-component wind tunnel balance — senses the forces and moments on the rotating device through a weakened shaft section instrumented with a series of strain gauges. This “rotating balance” was designed to directly measure the steady and unsteady hydrodynamic loads on an inducer, thereby defining the amplitude and frequency content associated with operating in various cavitation modes. The rotating balance was calibrated statically using a dead-weight load system in order to generate the 6 × 12 calibration matrix later used to convert measured voltages to engineering units. Structural modeling suggested that the rotating assembly first bending mode would be significantly reduced with the balance’s inclusion. This reduction in structural stiffness was later confirmed experimentally with a hammer-impact test. This effect, coupled with the relatively large damping associated with the rotating balance waterproofing material, limited the device’s bandwidth to approximately 50 Hertz. Other pre-test validations included sensing the test article rotating assembly built-in imbalance for two configurations and directly measuring the assembly mass and buoyancy while submerged under water. Both tests matched predictions and confirmed the device’s sensitivity while stationary and rotating. The rotating balance was then demonstrated in a water test of a full-scale Space Shuttle Main Engine high-pressure liquid oxygen pump inducer. Experimental data was collected a scaled operating conditions at three flow coefficients across a range of cavitation numbers for the single inducer geometry and radial clearance. Two distinct cavitation modes were observed: symmetric tip vortex cavitation and alternate-blade cavitation. Although previous experimental tests on the same inducer demonstrated two additional cavitation modes at lower inlet pressures, these conditions proved unreachable with the rotating balance installed due to the intense dynamic environment. The sensed radial load was less influenced by flow coefficient than by cavitation number or cavitation mode although the flow coefficient range was relatively narrow. Transition from symmetric tip vortex to alternate-blade cavitation corresponded to changes in both radial load magnitude and radial load orientation relative to the inducer. Sensed moments indicated that the effective load center moved downstream during this change in cavitation mode. An occurrence of “higher-order cavitation” was also detected in both the stationary pressures and the rotating balance data although the frequency of the phenomena was well above the reliable bandwidth of the rotating balance. In summary the experimental tests proved both the concept and device’s capability despite the limitations and confirmed that hydrodynamically-induced forces and moments develop in response to the unbalanced pressure field, which is, in turn, a product of the cavitation environment.

Résumé :
In recent years, the HKSAR government departments have been playing a leading role to study the feasibility of rock cavern development in Hong Kong. These studies include the relocation of existing surface sewage treatment works, service reservoirs, refuse transfer stations, archive centre and laboratory to rock caverns. After completion of the relocation, the previously occupied surface land can be released for other developments beneficial to the communities. Conventional permanent support systems comprise the cast-in-situ concrete lining with sheet waterproofing membrane. These have been applied in most of the highway and railway tunnels in Hong Kong. However, it involves the use of bulky steel shutter, heavy rebar fixing and an extra set of redundant temporary supports, which leads to very expensive and time-consuming construction. With the advance development in construction technologies, permanent rock reinforcements with sprayed waterproofing membrane could be a cost-effective engineering solution. With the integration of temporary and permanent supports, the tight daily drill-and-blast cycle and timely permanent support installation is greatly enhanced. This paper provides a general review of different conventional and innovative permanent support systems for rock cavern development with the purpose of achieving more efficient design and construction. It also discusses the application according to the unique requirements for various cavern facilities.
