Reflection of a Plane Underground Blast Wave from an Underlying Layer,

Abstract

The problem of reflection of a plane detonation wave from a fixed barrier and a water saturated soil in an elasto plastic medium is studied, taking into account the effect of the free surface. A soft soil with a varying dependence on stresses and deformations is used as a model. The basic equations of the dynamics of a compact medium are solved in the Lagrange coordinates. The case is then considered in which the base layer represents a water saturated soil. The water saturated soil is assumed to be nonlinear elastic medium. It is shown that reflections of a detonated wave from a water saturated soil and from a fixed barrier are governed by qualitatively identical mechanisms. (Author)
