Response of Saturated Soils to Dynamic Loading.

Abstract
The transient response of saturated porous soils to time dependent boundary conditions is analyzed. Galerkin finite element method is used to set up the spatial discretization of Biot's equations of wave propagation through linearly elastic fluid-saturated porous medium. Wilson's beta-gamma-theta algorithm is used to integrate the equations of motion. The procedure is applied to several one-dimensional steady state and transient problems. Excellent agreement with the analytic solutions was obtained with 'proper' selection of time-integration parameters.
