The method of spatial characteristics is considered and analyzed and its possibilities for studing of wave processes in deformable solid bodies of various structure and a rheology are investigated. Merits and demerits of a method are considered, and also the circle of tasks which it is necessary to solve for building of the characteristic form of mathematical model of dynamics and dynamic destruction of researched bodies and for its usage in numerical simulation. The initial and characteristic form of dynamical equations of the anisotropic symmetrically elastic bodies is shown. By means of the considered method numerically on PC the research problem of destruction of the two-storey house is solved at an earthquake load.
