本文利用有限单元法和解析法推导了求解上软下硬地基、夹层地基及道路结构瑞利波弥散曲线及位移分布的计算公式.得到了兼有有限单元法计算简单及解析法精度高之优点的计算方法,且编制了相应的计算机程序.并着重讨论了匀质软夹层地基瑞利波的弥散特性.

The formulation of determining Rayleigh wave dispersion curves and displacement shapes in regular layered soils,intercalary soils and pavement structures is developed in this paper. The authors present algorithm with both calculating simplicity of finite element method and high accuracy of analytical method and also present its computer program. The Rayleigh wave dispersion characteristic in soil profiles where a softer layer is trapped between harder ones is emphatically discussed.
