Numerous works in geotechnical and earthquake engineering fields have ignored the effect of interaction between solid grains and pore fluid on wave propagation and attenuation in porous media such as soil and rock we will study this effect by applying constitutive equations governing the behavior of saturated porous media in order to derive an analytical closed form solution for frequency dependent propagation and attenuation of compressional waves. two kinds of compressional waves are generated as a result of in -phase and out -of -phase movement of solid and fluid.
