【Abstract】 Now the subway construction is being rapidly developped and it is very important to assess it’s aseismatic capability.In the paper the behavior of subway tunnel due to seismic damage is discassed and how to decrease the extent of the damage is investigated.Furthermore the method of analyzing the dynamic response of the tunnel subjected to earthquake loading is expounded.The problems that should be further studied are reviewed in order to provide basis for subway tunnel design and to set up defense against earthquake.更多还原
