Abstract

The purpose of this study is to evolve the Swedish Weight Sounding test (Hereinafter referred to as SWS test) results from the conventional "relative index indicating the hardness of the ground" to "values with clear physical meaning". For this purpose, we analyzed the results of the edge penetration box shear test simulating a SWS test, the tri-axial compression test, and the SWS test using a full-scale embankment. The results indicated that the Nsw value and the torque value in the SWS test were not indicators of soil shear strength but indicators of soil volume compression characteristics. In addition, the shape of the screw point in the SWS test was simulated as "screw", and the acting force was considered from a mechanical engineering point of view. The results showed that the SWS test did not "screw in" the screw point, but penetrated by "compressing" the ground by rotating the screw point.
