| Abstract: | Based on the generally adopted soil model for engineering, an analytic solution of spherical wave propagation problem in a special case for an equally pressurized spherical cavity in saturated space by Laplace transformation which is compared with that of the same problem in a onep_hase elastic space. The influence of fluid on dynamic response of saturated soil is examined. The authors propose an effective way for dynamic analysis of underground structure. |
