Dynamic interaction of the two incompressible plates and soil set with a layered elastic half-space

Genesis of the problem descends from the need to implement shelters for military and civil defense purposes. In designing of the stationary shelters structures we must take into account the risks arising from the ability to use of the nuclear means of destruction. Admitted to the analysis system is a model that reflects the reality structure, consisting of the shelter with the soil and concrete overlay. This system rests on the layer soil surface. The analyzed dynamic interaction is caused by air shock wave. The main interaction factors are the wave stress processes in all soil layers. These processes are subject to wave interference with unsteady boundary conditions. Taking into account the spatial aspects of the problem we were used our own one-dimensional discrete calculation model which is characterized by the high accuracy of the wave processes analysis, expressed by the zero-error of the method. This model has a specific structure of each elementary discrete component. These are two half-masses with deformable connector. As a result, of the numerical experiments one obtained extensive information about the properties of the dynamic interaction of the consider set with the multi layered subsoil. (C) 2017 The Authors.
