摘要：

In this paper, the effect of boundary slip on the reflection and refraction of elastic waves at the interface of fluid-saturated porous media is investigated based on the virtually enlarged pore (VEP) model. The theoretical formula for the energy reflection and refraction of elastic waves is derived by introducing a potential function. The dependence of energy reflection and refraction coefficients on permeability and pore fluid viscosity is investigated using the VEP model. The numerical results are obtained and displayed graphically. It is observed that boundary slip has a noticeable effect on the energy reflection and refraction coefficients of elastic waves. The boundary slip effect makes the energy reflection and refraction coefficients more sensitive to the permeability and the viscosity of pore fluid.
