Diagnosis of earth-fill dams by synthesized approach of sounding and surface wave method Nishimura, Shin-ichi; Shibata, Toshifumi; Shuku, Takayuki


The spatial distribution of the strength inside the earth-fill is identified by the sounding tests. In this research, the Swedish Weight Sounding (SWS) is employed, and the spatially high-density test is performed to identify the spatial correlation structure. Furthermore, the synthesized approach of the SWS and Surface Wave Method (SWM), which is one of the geophysical method, is proposed to compensate the shortage of each approach. Consequently, the correlation structure of an earth-fill could be identified accurately, and the high resolution of the spatial distribution could be visualized based on the survey results.
