Study of wave motions in fluid-saturated porous rocks

Abstract

In this investigation, Biot’s theory was employed in the study of wave motions in fluid-saturated porous rocks. Consistent with the described experimental arrangement, Biot’s equations were solved using a Laplace transformation. The theory predicts two dilatational waves: a slightly dispersed fast wave propagating ahead of a heavily dispersed and attenuated slow wave. By comparing these results with experimental results, it becomes evident that the measured waves are in fact the fast waves. Subject Classification: [43]20.15, [43]20.40.
