Dynamic responses of ground vibration due to a moving load by using cole-cole model

Abstract

The dynamic responses of viscoelastic ground vibration due to moving loads by using Cole-Cole model is investigated in this study. First, the paper gives the equation of motion in terms of the displacements for the homogeneous isotropic viscoelastic medium in the frequency domain. Then, the governing equations can be reduced to two Helmholtz equations and the displacement of the viscoelastic medium can be expressed via the potentials. By applying the double Fourier transform with respect to the horizontal coordinates, the general solution for the potentials of the visoelastic medium in the frequency wavenumber domain can be derived. © 2012 Published by Elsevier Ltd.
