Dynamic Response of an Elastic Foundation on Transversely Isotropic Saturated Soil to Harmonic Torsional Loading

Abstract

An analytical method is presented to investigate the torsional dynamic response of an elastic foundation resting on transversely isotropic saturated soil subjected to harmonic loading. The dual integral equations of an elastic foundation are established according to the mixed boundary-value conditions at the interface and the dynamic torsional characterizes, which are further converted into a Fredholm integral equation of the second kind. The torsional dynamic response problem is solved by solving the Fredholm integral equation. By comparing present numerical solution with that of other’s, the correctness of this paper has been verified.
