Abstract

Objective: This paper studies the subway tunnel seismic nonlinear dynamic response, so that can get some helpful conclusions, which is helpful for seismic designing of metro tunnel. Methods:A series of probems on dynamic FEM are discussed and suggestions about setting of soil dynamic constitutive model and soil-structure contact model are given in the paper.With the example of Tianjin No.1 subway and No.2 sub-way, nonlinear analysis of dynamic response including displacement,stress and strain of circular tunnel and displacement of the surface of ground are conducted to draw some helpful conclusions. Results: Application of dynamic finite element method for seismic response of metro tunnel to do nonlinear analysis, can get a series of laws and conclusions. These laws apply to circular shield tunnel. Conclusion: Application of dynamic finite element method for seismic response of metro tunnel to do nonlinear analysis, draw some useful rules and conclusions, which will provide reference and basis for seismic design and research of the subway tunnel.
