The purpose of this article is to study the problem of propagation of waves that result of earthquake in different geological media: homogeneous, multilayer, gradient, with fractured layer and cave. The problem of analysis of wave impact on ground structures: buildings and dams is posed by authors. Numerical solutions of problems of wave propagation in heterogeneous media are obtained. On the basis of analysis of wave patterns the types of waves, propagated from the focus of the earthquake, are qualified. The comparison of impact of elastic waves on day surface for the cases of different geological media is done. Synthetic seismograms for these media are obtained. The influence of elastic waves on stability of ground structures is qualitatively examined. Grid-characteristic method for triangle meshes with formulation of boundary conditions on interfaces of rock – crack, building – rock, rock – water and dam – water, and also on free surfaces in an explicit form is used in this article.
Keywords: computational methods; computer science; mathematical modeling; parallel computing; continuum mechanics; safety of buildings.
