Forecasting of seismic influences on the foundations of industrial and civil buildings and structures under the complex engineering-geological conditions is an actual task of modern soil dynamics. At the present stage, such a forecast is carried out mainly by numerical methods using various mathematical models of the soil environment. In this paper, we determine the characteristics of the physical damping of sand and clay soils based on the results of special laboratory studies. The description of laboratory equipment for dynamic testing of soils is given. The analysis of the parameters obtained during the tests is performed. The transition from parameters obtained directly from the results of triaxial dynamic tests to parameters of mathematical models of soils used in modern geotechnical software complexes is shown. The numerical solution of several dynamic problems by the finite elements method is performed with due regard for various damping characteristics of the ground base of a high-rise buildings with a developed underground part. Recommendations are made for choosing a mathematical model of soils under the dynamic impact and the required set of parameters, and as well as an analysis of the solutions obtained is presented.
