Longitudinal Shock Waves in Soil
Abstract The stiffness of soils in compression increases with increasing pressure. This property makes the strain-stress relation nonlinear and strongly influences the propagation of compression waves: a smooth wave front steepens and turns into a shock front. This paper discusses some theoretical questions related to the formation and propagation of longitudinal shock waves in soil within the pressure range typical of geotechnical engineering problems (up to a few megapascals). In particular, the topics discussed in the paper are the critical distance for dry and saturated soils (the distance covered by a smooth front before it becomes discontinuous), the jump conditions on a discontinuity, and smooth viscous shocks.
