STEADY STATE WAVES IN A POROUS ELASTIC MEDIUM. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANCIS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

Assuming the soil consists of two distinct phases - granular structure and water - the theory of mixtures was used to derive elastic wave equations in conditions of plane deformation and one-dimensional propagation. The longitudinal wave propagation equation is applied to determine the steady state response of a soil layer excited by cyclic stress or strain at the boundaries. The results, presented in dimensionless form, allow the evaluation of the amplitude and the phase angle of the displacements at the top of the layer as functions of the frequency and amplitude of the excitation, of the thickness of the layer and of the compressibility and permeability of the soil. For the covering abstract of the conference see IRRD 287689. (TRRL)
