Centrifuge model tests were conducted to investigate the failure behavior of the composite ground improved by Sand Compaction Pile method, which consisted of sand piles and clay layer. In the model tests, the improved ground under a caisson block was leaded to failure by backfill loading. Results of model tests showed that the improved portion deformed toward the sea side with bending deformation mode. Circular slip analyses which simulated the model tests estimated large ground stability. Limit equilibrium analyses considering bending and sliding modes were carried out to be compared with the centrifuge model test on the failure behaviors. The results demonstrated that the limit equilibrium method on the bending mode closely approximated the model test of the improved ground under backfill loading.
