Note—EV: expected value, SD: standard deviation, CV: coefficient of variation. For A_c1–A_c6, the alluvial clay ground layer was divided into 6 layers in the depth direction from categorization of soil characteristics, acquired from boring test results and lab consolidation test results, and the layers were numbered from the top layer to the bottom layer. Similarly, for D_c1–D_c4 also, according to the categorization of soil characteristics, the diluvial clay ground layers were numbered from the top layer to the bottom layer.
