Abstract : The problems associated with the propagation of explosive waves in soil are of known urgency. It is interesting to calculate the wave pattern developing in soil close to the focus of the explosion (underground or above ground) or during the passage of the shock wave from the air or water into the soil. At considerable distances from the focus, this pattern can be described by the equations taken from the theory of elasticity; however, at closer distances, these equations are unsuitable and must be replaced by another system of formulas, taking into account the complex nature of the deformation and flow of the medium at high stresses, and only at the boundary in case of reduction of stresses do we transfer to the equations taken from the linear theory of elasticity. Such a type of mathematical model of the medium has been suggested for describing the movements of soft soil (sand, clay etc). (Author)
