Abstract
The purpose of this paper is to investigate the relation between the dynamic characteristics of an embedded foundation structure and replaced soil, which is burried to bridge the gap between side wall of structure and surface stratum. The analysis is performed by making use of three-dimensional wave propagation theory. Many properties of replaced soil, which effect on the dynamic characteristics of structure, can be considered, but in this paper the numerical investigation are done by picking up hardness and width of replaced soil among them. It becames clear from the numerical analysis that these properties of replaced soil influence considerably upon the dynamic characteristics of an embedded foundation structure.
