弹性层和饱和半空间模型是一种具有理论价值及工程背景的地基模型.本文针对这一模型,采用积分变换方法研究了其表面受稳态激振下的动力响应.本文针对两种界面连续条件推导了响应的积分形式解,并将其蜕化为饱和弹性半空间及固体弹性半空间的积分形式解,文末利用数值积分技术作了有意义的算例分析.本文为饱和分层地基的动力响应计算提供了有效方法,同时也为进一步利用边界元法解决此类地基的波传播问题、动力相互作用问题开拓了一条途径.
The elastic layer and saturated half-space model is a ground-based model with theoretical value and engineering background. In this paper, the integral transformation method is used to study the dynamic response of the surface under steady-state excitation. The integral form solution of the response is deduced from the condition, and it is decomposed into an integral solution of a saturated elastic half-space and a solid elastic half-space. At the end of the paper, a numerical example is used to make a meaningful case analysis. This article is the dynamics of the saturated layered foundation. The response calculation provides an effective method, and also opens up a way for the further use of boundary element method to solve wave propagation problems and dynamic interaction problems of such foundations.
