This paper describes a dynamical analytic study concerning soil-structure interaction problems in case of structure embedded in an soil ground. The analysis is performed on basis of two-dimensional wave propagation theory inwatersaturatedsoilground. In this paper are derived the sets of governing equations of soil-structure interaction system subjected to base rock excitation. The following conclusion may be drawn from the present numerical examples: (1)The interaction effect between water saturated soil ground and the structure increases with lower permeability in aggregate body. (2)When the structure is subjected tobase rock motion, the dynamic earth pressure depends on excitation frequancy. (3)If the structure with smallaspect ratio is pertinently buried insoil ground, the rotational response of it could be been minimum. (4)The effect of embedment is to increase the soil resistance to motion of the structure.
