THE HARMONIC VIBRATION OF INFINITE PLATE ON TRANSVERSELY ISOTROPIC SATURATED SOIL GROUND

This paper studies the dynamic response of an infinite rectangular plateon transversely isotropic saturated soil ground under a harmonicexcitation.Based on the general solutions of the 3-d wave motion equations inrectangular coordinates for transversely isotropic saturated soil mediapresented by the author, the equation for dynamic interaction between thesaturated soils and plate is established and solved by using the techniqueof double Fourier transform. Integral solutions of displacements for the plate excited by a harmonic source are presented. The calculation results indicate an obvious difference of the vibration properties of the infiniteplate based on the model of isotropic saturated soils and that based on the transversely isotropic saturated soils.
