Abstract
The purpose of this study is to evolve the Swedish Weight Sounding test (Hereinafter referred to as the 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 consolidation test, the edge penetration box shear test simulating the SWS test, and the SWS tests using the full-scale embankment. As a result, it was shown that Nsw values of the SWS test are related to the volume compression characteristics of the soil, and that torque values of the SWS test can be estimated by shear force of the edge penetration box shear test. Since these laboratory tests are conducted by controlling the degree of soil compaction, Nsw values and torque values of the SWS test can be associated with the degree of soil compaction. Based on these findings, it was shown that the SWS test results could be used for liquefaction risk assessment and ground subsidence prediction using the degree of soil compaction as an index.
