Abstract:The shaking table tests on subway station joint structure model were introduced and simulated by FDM software FLAC3D.The calculation range of model was consist with the model box.Davidenkov model was employed to simulate the dynamic nonlinear characteristics,and the constant acceleration boundary condition was used.The rule of acceleration response of modelled soil and structure,the dynamic strain of structure and the dynamic soil pressure between soil and structure were obtained.The calculated results agreed well with the test results,showing that the simulation was correct,and it could be used to establish the 3D calculation method for subway station structure under seismic load.
