Multi-channel Analysis of Surface Waves (MASW) and Seismic Cone Penetration Test (SCPT) have been
recently developed to obtain S-wave velocity profiles which were conventionally investigated by a down-hole seismic
survey. For unconsolidated sedimentary sites, we studied these three methods, and compared the results with a drilling log.
All the methods showed that the changes in the S-wave velocities were consistent with the changes in the sedimentary
facies. In addition, the SCPT was most sensitive to changes in sedimentary facies among the three profiles. The results of
the SCPT showed that there exists a low velocity zone, which is mainly composed of clayey sand, at the depth of 8~12
m in the sediments.
