Annotation:

A mathematical model of gravel penetration into soil massif under dynamic impact of explosion of a cylindrical explosive charge is considered, It allows to describe the stress-strain state of soil and gravel particles with different physical-mechanical and geometrical parameters of the analyzed objects. When breaking into the ground the gravel compress it, and at equal distances larger values of volumetric deformations are achieved in soil with high free porosity.
