On a model of interaction of lithospheric structures

The paper presents the effective approach to the study of the stress-strain state of lithospheric structures simulated by the Kirchhoff plate system on the elastic layer near the splits. A new method for solving the problem corresponding to the rectilinear fault model was implemented in a flat setting, calculations were performed, and the obtained results were analyzed with varying physical and mechanical characteristics of the plates and the conditions for their contact. The use of this approach will simplify the algorithm for determining the displacements of the coating and contact stresses, and also draw conclusions about the effect of the fault type (boundary conditions at the plate interface) on the nature of the wave process in the simulated geophysical environment, in particular, the change in the shape of the signal when passing through a split, characteristics of splits in the upper part of the Earth's crust.
