Abstract In order to intensively study the influence of different subsoil properties on the seismic performance of soil-pile-nuclear island structure system and the related seismic damage mechanism of pile foundations，three kinds of subsoil models with different stiffness were prepared for shaking table test，and the macro phenomena and test data were analysed and compared. The test results show that subsoil stiffness has a great influence on the seismic-soil-pile-superstructure interaction system. With the decrease of the subsoil stiffness，the phenomenon of soil-structure separation is more obvious，and the seismic damage of pile foundation is more serious. Due to large inertia force of the superstructure and compliance of the subsoil，the foundation pile is damaged not only at the pile head，but also at the depth of 5–6 times the pile diameter. In order to ensure the seismic safety of nuclear power engineering foundation，it is recommended to strengthen or select the soil layer with shear wave velocity greater than 300 m/s as the foundation subsoil.
