Surface wave propagation in a liquid-saturated porous solid layer lying over a heterogeneous elastic solid half-space

摘要

Dispersion equation is derived for the propagation of Rayleigh type surface waves in a liquid saturated porous solid layer lying over an inhomogeneous elastic solid half-space. Effect of heterogeneity on the phase velocity is studied by taking different numerical values of Heterogeneity factor for particular models. Dispersion curves have been drawn showing the Effect of heterogeneity on the phase velocity.
