| Abstract: | Based on the generally adopted soil model for engineering, taking saturated asnds as two phase medium,the problem about transient dynamic response of spherical cavity in saturated sands is solved and analytic solution for an equally pressurized spherical cavity is obtained.Compared with the same problem in one phase medium,the influence of fluid on dynamic response of saturated sands is investigated.An effective way for dynamic analysis of underground structure is presented in this paper. |
