A METHOD OF ESTIMATION OF ELASTIC PROPERTIES OF LAYERED SOILS USING P-SV WAVES BY HARMONIC POINT LOAD ON GROUND SURFACE

Abstract

This paper presents a method of estimating the elastic properties of the soils and their variation with depth using the characteristics of P-SV wave propagation in layered media and their dynamic response due to the vertical harmonic point load applied on the soil surface. To demonstrate the capability of the presented method, the two numerical examples are presented, for the estimation of the S wave velocity, P wave velocity and thickness of each soil layer using a single layered medium and the three-layered media overlying on a half space medium. In the numerical examples, a stiffness matrix method for acculately calculating wave field is used.
