摘要：In this paper, we determine the characteristics of the physical damping of sand and clay soil by the results of special laboratory tests. The transition from parameters obtained directly from the results of triaxial dynamic tests to parameters of mathematical models of soils used in modern software complexes is shown. The solution of several dynamic FEM problems is exemplified by PLAXIS PC taking into account different damping characteristics of the ground base of a multi-storey building with a developed underground part. Recommendations are given for selecting a soil model for dynamic impact and dynamic soil parameters, and an analysis of the solutions obtained.
