摘要: 本文采用工程上通用的土力学模型,利用Laplace变换求解了饱和土中球面波的传播问题,对一种特殊情形下的均匀受压球形空腔得到了解析解,并与弹性单相介质中均匀受压球形空腔进行了对比,以考察流体对饱和土体动力响应的影响.本文为分析地下结构动力响应提供了一种有效的方法,有重要的工程应用价值.Abstract: Based on the generally adopted soil model for engineering,ananalytic solution of spherical wave propagation problem in a special case for an equally pressurized spherical cavity in saturated space by Laplace transfo rmation 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 dy namic analysis of under ground structure.
