Abstract

This paper studies the behavior of grounds and rock mass under explosive loads using a new worked out model of deformation of ground and rock mass accounting structural destruction of grounds. Here mechanical characteristics of grounds are the functions on the degree of structural destruction (on the second invariant of the deviator of deformation). The problem on excitation propagation from hemispherical cavity cut from ground half-space, to the sides of this cavity a load is applied, imitating the action of explosion. The problem is solved numerically - by the method of finite differences according to the scheme offered by Wilkins M.L. Solution of problem defines the dimensions of the craters and outburst ground as well as the zones of destruction of ground and rock mass.

Determination of the Zone of Destruction of Soil and Rock Mass at Explosive Loads

San Diego, California

This paper studies the behavior of grounds and rock mass under explosive loads using a new worked out model of deformation of ground and rock mass accounting structural destruction of grounds. Here mechanical characteristics of grounds are the functions on the degree of structural destruction (on the second invariant of the deviator of deformation). The problem on excitation propagation from hemispherical cavity cut from ground half-space, to the sides of this cavity a load is applied, imitating the action of explosion. The problem is solved numerically - by the method of finite differences according to the scheme offered by Wilkins M.L. Solution of problem defines the dimensions of the craters and outburst ground as well as the zones of destruction of ground and rock mass.
