| | Abstract | | In order to establish a harmonic wave method to estimate the depth of the geological layer , this paper has examined some of the basic relationships between the depth of the relatively harder soil thin layer and the characteristics of the P-SV wave propagation in layered media and their dynamic response due to the vertical harmonic point load applied on the ground surface. In this examination, the P-SV wave field has been simulated by FEM in soil layered media. It has been found from this numerical investigation that the depth of the relatively harder soil thin layer can be estimated from the information of the change of the phase velocity on ground surface at the resonant frequency of the soil layer. |
