Abstract:The shaking table test on typical metro station structure is simulated by FLAC3D. The calculation model includes the following four aspects. (1) The calculation area is identical with the model box. (2) The Davidenkov model is employed to simulate the dynamic nonlinear characteristics of model soil;and the structural model is regarded as in elastic state during test. (3) The dynamic boundary conditions are set as acceleration boundaries because the deformation of model box can be neglected. (4) The seismic loads accord with the waves used in the test. The test and calculation results include the rules of acceleration response of model soil and metro station structure model,the dynamic strain of metro station structure model and the dynamic soil pressure between model soil and structure model. The calculation results agree well with the test results,which shows the rationality of the proposed model. It can be used to simulate the dynamic characteristics of model soil,calculate the dynamic response of metro station structure and analyze the dynamic interaction between soil and structure. The study provides foundations to establish the 3D calculation method for metro station structure under seismic load in soft soil areas.
