The formulation includes the computation of phase velocities, mode shapes and amplitude response functions (medium responses) of Rayleigh and Love waves propagating in a layered half-space. By comparing the computed values with the theoretical ones, it is concluded that the thin layered element method can be used as a very good alternative to the theoretical solution method. In addition to the eigenvalues, H/V amplitude ratios of the surface waves have been examined by this method, in which a synthesis of higher mode contributions of both Rayleigh and Love waves is formulated. The proposed method was applied to a site where a PS-logging is available. Finally, wave propagation in an irregular ground due to an incident Rayleigh wave is formulated based on the finite element method. It was found that wave propagation is significantly influenced by the irregularity.
