DYNAMIC DISPLACEMENT SOLUTIONS OF A FLUID-SATURATED POROELASTIC HALF-SPACE DUE TO A STEADY-STATE HARMONIC VERTICAL POINT EXCITATION IN THE INTERIOR OF THE MEDIUM

Abstract

This paper deals with dynamic displacement solutions of a fluid-saturated poroelastic half-space due to a vertical point excitation in the interior of the medium. The solutions are derived by a transfer matrix method using a vector-matrix which is obtained by double Fourier transformation. As numerical examples, this paper shows results of the vertical displacement due to a vertical point excitation with nondimensional frequency changing.
