In the SCP method, when sand piles are driven into the saturated clayey ground, clay is disturbed significantly accompanied by the excess pore water pressure built up, resulting in clay's shear strength decrease. Reports on shear strength characteristics in SCP method are few, hence some uncertain points are still remained. In the ground improvement at Tokuyama-Kudamatsu port, over 1,000 laboratory tests were performed to observe the effects of SCP with the low sand replacement ratio on the stability of the ground. Based on these results, the change in the density, natural water content, consolidation characteristics, shear sterngth were clarified.
