Analysis of Soil-Structure Interaction Effects of NPP Structures on Nonhomogeneous Subsoil

[摘要] This paper describes the soil-structure inte-raction (SSI) effects to the Nuclear Power Plant (NPP) structure with reactor VVER-1200. The simplified 1D and numerical 3D FE models of the nonhomogeneous subsoil are investigated. The methodology of the calculation of the frequency dependent complex functions of the soil stiffness and damping is presented.
