“…Kawajiri et al [8] reports that the difference in dry density can be evaluated by the S-wave velocity obtained from the surface-wave method in test embankments with different D c . In addition, it has been reported that the S-wave velocity obtained from the surface-wave method locally decreases in the geosynthetics reinforced soil wall where the deformation occurred [9,10]. The surface-wave method is also applied to the property evaluation of road embankments [11].…”

This report describes a case where counterweight fill using a high-intensity geotextile is applied as a measure to prevent landslide. In addition, this report shows the strain acting on the reinforcing material during and after construction, the earth pressure gauge installed in the embankment, and the field measurement results of the surface-wave method. From a series of observation results, no strain acting on the geotextiles was confirmed, nor was there any abnormality in the reinforced embankment. Furthermore, no local decrease in the S-wave velocity could be confirmed, and no change in the internal state of the reinforced embankment could be confirmed.
