A large-scale shaking table test of three-story subway station has been performed,and some reliable testing data are acquired.The model and soil material mechanical parameters are achieved through indoor experiments.Based on ABAQUS FEM calculation platform,two-dimensional FEM model of the shaking table test is constructed.Problems such as concrete constitutive model and its parameters,soil constitutive and its parameters,damping settings,and boundary condition settings are handled.Comparative analysis is performed between testing data and simulation data.The results show that: The FEM model could closely simulate shaking table test if we construct the model following the method recommended in this paper.The numerical data accord well with the testing data both in trend and magnitude.
