Abstract

In this work, are presented two-dimensional semi-analytical and numerical approaches to solve the problem of an elastic layer overlying a half-space and subjected to an harmonic vertical load. The analytical approach uses a Fourier transform of the governing equations then the displacements at the ground surface are obtained by using the inverse Fast Fourier Transform. As a numerical model, a coupled finite and infinite element scheme is used. A parametric study is carried out to see the effect of the layer parameters and the ground structure on the surface vertical displacement. The results of both approaches show good agreement and the drawn conclusions are similar to those obtained from a three-dimensional semi-analytical model developed earlier.
