This research article is focused on the study of shear wave behavior in a fluid-saturated porous layer (FSPL) having transverse isotropy, positioned between a homogeneous layer and an elastic half space characterized with triangular-shaped irregularity which exists at interface of contact between the FSPL and half space. By utilizing the Fourier transform approach and perturbation method, the dispersion relation for the shear waves is obtained. The obtained dispersion equation is function of factors such as wave number, phase velocity, and frequency of shear waves. It has been observed that wave number, irregularity depth, and initial stress all have a substantial influence on phase velocity. These findings could help in geophysical exploration and understanding earthquake dynamics and damage.

摘要

This research article is focused on the study of shear wave behavior in a fluid-saturated porous layer (FSPL) having transverse isotropy, positioned between a homogeneous layer and an elastic half space characterized with triangular-shaped irregularity which exists at interface of contact between the FSPL and half space. By utilizing the Fourier transform approach and perturbation method, the dispersion relation for the shear waves is obtained. The obtained dispersion equation is function of factors such as wave number, phase velocity, and frequency of shear waves. It has been observed that wave number, irregularity depth, and initial stress all have a substantial influence on phase velocity. These findings could help in geophysical exploration and understanding earthquake dynamics and damage.
