| Research Abstract |
Tunnels are thought as excel in seismic adequacy, there for the seismic behavior of the tunnels are did not clearly discussed. However, earthquake damages of the tunnel lining are reported in the field, which with the low overburden or which excavated tunnel in soft ground. Therefore, a series of the model experiments and numerical analyses are carried out to make clear the seismic behavior of the tunnel lining and ground which excavated in the above mentioned ground. Thereafter, effect of the auxiliary method including the ground improvement method and foot reinforcement method, and the mechanism of the effect are discussed. Experimental results show that, the load act on the tunnel lining is increasing during earthquake, even in the high overburden condition. Moreover, the deformation of the tunnel lining and the ground can be prevented by installing the auxiliary method.
