Abstract
In recent years, the usefulness of surface-wave method has been reported as a method for efficiently evaluation of reinforcing soil walls. It is necessary to evaluation the relevance between the deformation amount of reinforcing soil walls and S-wave velocity, VS from the surface-wave method in the future in order to apply the surface-wave method as the soundness evaluation method of the reinforced soil walls. Therefore, in this study, the surface-wave method, wall panel tilt angle measurement, reinforcement material extraction test, boring survey were performed on geosynthetics reinforced soil wall where deformation exceeding construction control value occurred. In addition, we examined the relevance of various in situ tests results. As a result, when the wall panel tilt angle was large, VS did not monotonically increase with the increase in depth but locally decreased. In other words, we have found the possibility to evaluate the soundness of reinforced soil wall by using VS that can be obtained from the surface-wave method.
