| Abstract: | 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. |
