In this paper, we investigate the relationship between S wave velocity distribution and dry density immediately after completion of two test embankments constructed by changing degree of compaction. In addition, we compare the change of S-wave velocity distribution before and after the rainfall, and examined the applicability of surface wave exploration to the change of the properties inside the embankment. As a result, the distribution of the dry density and the S wave velocity distribution obtained from the surface wave survey were well matched. In low embankment, the saturation increased due to rainwater infiltration, and the S-wave velocity remarkably decreased after rainfall. From these results, it is possible to estimate the property change in the embankment by the S-wave velocity distribution obtained from the surface wave survey, and it was confirmed that the surface wave exploration can be applied as the primary screen for the property evaluation of the embankment.
