Analysis on the Seismic Response of Hangzhou Metro Tunnel in Soft Soils

Abstract:

A large number of earthquake disasters indicate that the underground structure, such as metro tunnel, is not safe and reliable as people think, and can also be destroyed and collapsed under dynamic load, e.g. earthquake. Therefore, it is necessary to study the seismic response analysis of underground structure in great detail for underground structure under dynamic loading, especially under the earthquake load. Hence, in view of the soft soil of Hangzhou, the 3D non-linear finite element software ADINA is used to study the seismic response of section tunnel of Hangzhou metro line 1, to summarize the earthquake response characteristics of the subway underground structure, and to provide the calculation results of metro tunnel’s seismic response and the change rule of lining deformation and stress. The conclusions obtained can provide some reference values in the seismic design of metro tunnel in soft soil regions.
