In this study, the applicability of surface-wave methods for health monitoring of port structures were examined. First, the variation of shear wave velocity in the ground due to suffusion and variation in water content is measured by bender element tests. Then, 2D FEM dynamic analysis was conducted for a simulation of surface-wave measurement on a sheet pile quaywall. As the result of the analysis, the estimated results of shear wave velocity profile by a surface wave method agree with the assumed soil profile in general. Finally, surface-waves were measured at a real field of a sheet pile quaywall, and the measured results were consistent with the result of swedish weight sounding test at the site. Furthermore, the difference between the shear wave velocity profiles at ebb tide and that at high tide was successfully measured by the surface wave method. Thus, the applicability of the surface wave method for port structures is demonstrated.
