In this paper, finite element method and analytical method are used to deduce the formulas for solving the Rayleigh wave dispersion curves and displacement distributions of the upper soft ground, hard ground, interlayer foundations and road structures. The advantages of simple finite element method and high accuracy of analytical method are obtained. The calculation method and the corresponding computer program have been compiled. The dispersion characteristics of the Rayleigh wave in a homogeneous soft interlayer soil have been discussed.
