THE WAVE THEORY OF SEISMIC SAFETY IN THE PROBLEM OF DETERMINING THE STRESS STATE IN A SHALLOW-BURIED STRUCTURE

This article discusses how digital technologies can be used to simulate non-stationary waves that occur in shallow structures during seismic impacts. A unique methodology, as well as a set of algorithms and calculation programs, was created to study, identify and analyze transient wave phenomena. To determine how reliable and accurate the developed software package is, we solved the problem of how two geometric objects - a triangle and a trapezoid-affect the elastic half-plane. The tasks were solved according to the following scheme: explicit, two-layer. We managed to find a solution to the problem associated with the impact of external seismic waves on a structure located at a shallow depth. The simulation is performed using a step-type function. In the course of the study, stresses were determined in the characteristic zones of the object under consideration – structures with a small depth of occurrence.
