Elastic wave reflection in viscoelastic half-space of saturated porous liquid state
The propagation characteristics of elastic waves in viscoelastic half-space with saturated porous fluid are studied.Based on the theories of porous media and viscoelastic media,as well as the jet flow effect,study the reflection problem of planar P-waves on the boundary of saturated porous viscoelastic media.Firstly,consider the constitutive equation and control equation of a saturated porous viscoelastic medium with solid-liquid coupling.Secondly,potential functions and permeable boundary conditions are introduced.Finally,through theoretical derivation,the jet flow effect on the boundary of saturated porous viscoelastic media and the influence of incident angle on the reflection coefficient are given.
