dc.description.abstract Lagrangian coordinates allow to simulate free and contact boundaries as well as to implement boundary conditions accurately and correctly. The difference scheme proposed by Wilkins but with certain modifications has taken as a basic scheme for solving the governing equations. This scheme is second order and is satisfactory for the problem that under our consideration. The corresponding state equations for the ground, fluid, explosive and detonation pro ducts are chosen. The developed methods and algorithms have tested and realized. Planning and execution of numerical experiments with analysis and visualization in graphs and 2D-images have implemented. In the framework of the described model the stress-strain state of buried structures has analyzed. The properties of structural materials, ground and filler have taken into account. The behavior of buried structures under explosive or seismic wave was studied. The influence of the surrounding environment on the deformation structure processes has investigated. en_US
