ABSTRACT

The dispersion characteristics of normal waves in porous-elastic layer with free surfaces are studied on the basis of the Biot theory both for open and closed pores. The analysis of the influence of dissipative effect, caused by the flow of the pore liquid relative to solid skeleton, on the dispersion spectrum was carried. It was discovered that the introduction of the above attenuation mechanism influences in varying manner the behavior of the "solid-like" and "fluid-like" waves. The "fluid-like" waves respond to the change of the parameters, describing the given kind of the dissipation, much stronger. The spectrum modification of the "solid-like" waves in a porous-elastic layer, if the attenuation is taken into account, in many respects is similar to that in the visco-elastic layer.
