To the layered soil of dynamic soil-structure interaction large-scale model test,commonly used equivalent linearity model is chosen to consider the non-linearity of soil and the dynamic characteristics of soil are obtained,then the earthquake response of three-dimensional finite element model is analyzed under different peak acceleration and different frequency spectrum features ground motion,and the seismic amplification of sites and soil filtering effect are studied.The present work lays a foundation for further research on soil-stricture interaction.
