The aim of this paper is to present the discrete-continual method of analysis of the coupled system “plate-soil foundation” in the context of microseismic and gravitational processes in a foundation. The distinctive method is the discrete-continual because it presupposes finite element approximation with respect to space coordinates while the problem remains continual in time. This reasonable combination of numerical and analytical approaches offers numerous advantages and provides a high degree of accuracy. Time discretization is not required and therefore this appreciable fact in its turn leads to the considerable reduction in the computing time and in the number of operations. Due to specifity of initial data standard step-by-step methods couldn39;t meet the challenge for the considering problem. Brief introduction to the problems of geological efficiency of microseismic processes in foundations is provided. The original formulation is based on elastic theory and linear creep theory. We use the soil model allowing propagation of plastic deformations and the nonlinear model of soil foundation under cyclic loadings, proposed by Professor Z.G. Ter-Martirosyan. Being foreground subject of this paper, the discrete-continual method is considered in the several aspects of theoretical basics, numerical implementation and software packages. Numerical example is presented as well.
