The purpose of this paper is to investigate dynamic properties of a saturated soil layer due to the variation of the elasticity of a soil skeleton. By applying the wave transfer method and FEM for mixture mechanics to the soil layer, dynamic properties of the soil layer based on the analysis of free vibration, steady state vibration and earthquake vibration are given. Obtained results are as follows. 1. The pore water in the soil affects the natural frequency and amplited ratio in the soil layer, that is, the stiffness and damping action varies due to the elasticity of the water in the layer. 2. This water content effect is dependent on the elasticity of soil skeleton and different according to the type of wave propagation. 3. In shearing motion, the soil layer is softened with the increase of elastic properties of soil skeleton and the damping properties in the layer is increased with same extent. 4. The water saturated in the pore in the dilatational motion, hardens the stiffness of the ground until the phase velocity of soil skeleton corresponding to the propagating velocity of the water and has ilttle effect on the properties of the layer in the velocity greater than that of water.
