Abstract: Thin spray-on membrane, which is a sprayed waterproofing membrane is considered as a measure of a conventional waterproofing sheet since it can be easily sprayed on sprayed concrete or excavated rock surface. Especially, it can be utilized in a single-shell tunnel because it can transfer loads acting on a sprayed concrete layer to the other sprayed concrete layer. However, the interfacial...
Abstract: Pertinent evaluation of structural integrity and safety of tunnels in operation is a prospect that tunnel engineers are striving for. In the meanwhile, clarifying the cause of tunnel anomalies is also essential to effective tunnel maintenance. Researches indicated that the pattern of lining cracks can be characterized to suggest possible candidates of anomaly causes. Nevertheless, quantitative...
Abstract: An waterproofing membrane has a relatively higher initial strength, faster construction time and higher waterproofing performance than the conventional sprayed concrete linings. Waterproofing membrane mainly consists of polymers and its supporting potential is from the adhesion at the interface and tensile strength which is distinct from the conventional method such as the shotcrete. However,...
