The spectral analysis of surface wave (SASW) method is an in situ testing method which is recently developed. This method uses a transient impact to generate surface wave on the ground surface, and measures the ground surface response to determine the shear wave velocity profiles of soil deposits. Different impact-type sources were used to generate broad range frequencies domain, and used multi-receivers to determine the complete dispersion curve. By applying an inversion process, the profile parameters obtained using the modified Satoh's method was compared with those of using down-hole test. The paper presents the study of in-situ investigation of Tsengwen earth dam using SASW method. The results show that the error is within 7.5% as the results obtained using SASW method comparing with those down-hole data. The method can evaluate the dynamic property of earth dam quickly and cost effectively.
