Stress Wave Propagation through Cohesive Soil

Abstract

Generally, there exist an inelastic deformation and an energy dissipation during the stress wave propagation through cohesive soil. In order to describe these characteristics, the authors proposed the constitutive equation of normally consolidated clay. The phenomenological nature of the parameters involved in the stress-strain relation was investigated in detail by using the triaxial test results and the stress wave propagation test results. In these test the pore water pressure was measured and its value was compared with the calculated result by using the constitutive equation of clay. As a result, the proposed stress-strain relation was very effective for interpreting the behavior of cohesive soil.
