Research Abstract

Tunnels in weakly cemented or no-cemented soils are susceptible to damages by ground motions or displacements caused by earthquake. In order to investigate complicated seismic soil-structure interaction of such tunnels, various model testing techniques has been developed, such as an active type shear box and a fault simulators. Three specific conditions were considered in this study, namely, 1) shallow tunnels which are subjected to shear deformation of grounds, 2) Tunnels in weak ground which is subjected to large earth pressure, and 3) tunnels in an alluvium subjected to fault displacement. From the model test results and numerical simulation, typical deformation and failure mechanism of these tunnels are scrutinized and effective countermeasures against them are discussed.
