At a flat surface with an infinite boundary, the surface wave’s energy is dissipated by wave propagation. At a non-flat geotechnical site such as railroad embankment, dam, cliff or slope, the waves will eventually be reflected at the boundary leading to complexity in a recorded time trace. Thus, accuracy of the resulting stiffness profile is not sufficiently reliable. In this study, surface wave propagation at a non-flat geotechnical site was investigated. A method based on signal processing technique namely, inverse Gabor spectrum (IGS) was proposed to eliminate the undesirable wave groups. The IGS filtered spectrum was further processed by spectral analysis of surface wave (SASW) technique. The results show that significant improvement can be made in the interpretation of phase spectrum of non-flat geotechnical sites.
