In recent years, it has been reported that the surface-wave method is useful as an efficient way to evaluate the current condition of a reinforced soil wall. In this study, we have applied the surface-wave method to five reinforced soil walls, having different degrees of deformation, in the Okhotsk area of Hokkaido to investigate the relationship between the distribution of VS and the slope angle of wall panels. The results show that as long as the slope angle is large, VS reduces locally rather than increasing proportionally to the depth. Accordingly, we find that the use of VS has the possibility of evaluating the degree of damage to reinforced soil walls.
