Abstract

This study examines the seismic behavior of a rigid wall in cross-anisotropic poroelastic layered soil, focusing on the frequency domain. Both analytical and numerical solutions are developed to tackle the problem. The analytical solution employs the finite Fourier transform, whereas the numerical solution uses the differential quadrature method. The proposed numerical solution considers various boundary conditions of the wall and base. The results are compared with those of existing studies on elastic soil, encompassing both homogeneous and heterogeneous cases, as well as poroelastic soil. The comparison demonstrates the accuracy of the proposed methods. Notably, the boundary conditions of the wall and base significantly affect the results at specific frequencies. In addition, the layered soil conditions have a relatively significant impact on the results across most frequencies.
