英文摘要	Based on Biot's model for fluid-saturated media, which takes the inertial, fluid viscous, mechanical couplings, compressibility of grains and fluid into account, the dispersion equations of plane waves in non-homogeneously saturated soil are established by using reverberation ray matrix method (RRMM) with the aid of Helmholtz theorem. The non-homogeneity considered is a gradient variation in material properties with depth. The propagation characteristic of elastic waves in non-homogeneously saturated soil is analyzed by numerical example in this paper. The results show that the wave number and dissipation change little for two kinds of compression along the variation direction of the material properties, however, the non-homogeneity has significant effect on the wave number and dissipation of shear wave.
