Abstract A simplified seismic analysis method of soft soil SSI system is studied in this paper. Based on the earlier stage tests and FEM analysis，a simplified dynamic model with small relative dynamic stiffness ratio of soil to superstructure is put forward，and the inversion solution of model parameters is presented. The seismic analysis method of soft soil SSI system with simplified dynamic model is derived. By comparison of computational solution and test result，the thought of simplified modeling is confirmed.
