Abstract
The method of analysis of soil deposites with fluid saturated soil layer is proposed. Free vibration, frequency response and seismic response of a stratified ground which is composed of two layers-dry soil layer and water contended layer-, are presented and discussed. The ground considered, is assumed to be dry above the water tabel and saturated with water under the level. Eigenvalue analysis for such a ground by using the finite element method is carried out and transfer properties by the wave propagation method are obtained. The numerical results show that the water in the soil deposit deteriorate the ground stiffness and increase the damping properties in shear motion, whereas in the longitudinal motion, the stiffness and damping in the ground are increases. The seismic response analysis of the same soil layer gives the similiar properties in shear motion.
