摘要
Based on Biot's theory of saturated porous media, the propagation of Rayleigh waves in nonhomogeneous saturated porous media is studied. The frequency equation of Rayleigh waves in inhomogeneous saturated porous media is derived in which the variation of shear modulus is taken into account, and the existence conditions are also given. It is pointed out that the shear modulus of the material parameters is a function of depth via a theoretical derivation, and the final expression of the solid skeleton and fluid displacement in the medium is obtained.
