Surface Rayleigh waves in porous media have been the subject of a number of investigations before (Dobrin, [1]; Press, Healy, [2]; Macdonald, [3]; Deresiewicz, Rice, [4]; Takeuchi, Saito, [5]; White, [6]; Liu Philip, Wen Jiangang, [7]). In the present paper the features of the Rayleigh waves propagating along the free surface of a porous medium saturated with liquid are investigated by means of two-velocity, twostress tensor model. The dispersion relation is obtained. The frequency dependence of phase velocity, linear decrement of attenuation and coefficients exhibiting damping of amplitude with depth for monochromatic, waves are studied. The pattern of deformation of the near-surface layer during Rayleigh wave propagation is considered.
