Abstract: Coupling analysis method of finite element and infinite element is proposed to be used in the structural anti-seismic analysis of metro tunnel on the basis of soil-structure interaction theory. For a better consideration of nonlinear characteristics of soil-structure interaction, Ramberg-Osgood skeleton curve is adopted here to model constitutive relationship of soils, and also GOODMAN element is adopted to model nonlinear working states on the interface between soils and structure. This paper conducts the dynamic analysis and comparison on seismic response of a tunnel structure with double-hole rectangular section and draws some helpful conclusions.

Key words: dynamic interaction, infinite element, coupling model, material nonlinearity, status-changing nonlinearity
