| Abstract: | Based on the generally adopted soil model for engineering, an analytic solution ofspherical wave propagation problem in a special case for an equally pressurizedspherical cavity in saturated space by Laplace transformation which is comparation which is compared withthat of the same problem in a one-phase elastic elastic space. The influence fo fluid on dynamic response of saturated soil is examined .The authors propose an effectivefor dynamic analysis of underground structure. |
