Centrifuge tests were carried out to investigate the settlement reduction effect of a SCP (sand compaction pile) and a GCP (gravel compaction pile). Numerical analyses by the FEM (finite element method) , which simulate the test conditions, also were carried out to compare the test results with those of the analyses. Settlements of SCP and GCP were measured during the centrifuge test for the area replacement ratio of 30%, 40%, 50%, 60% and 70%, respectively. Also examined were the coefficient of settlement reduction, the stress concentration ratio and the coefficient of stress concentration. The results of the study show that GCP was more effective than SCP in terms of settlement reduction.
