Sand compaction pile (SCP) is widely used in dealing with marine clay for the construction works. The process of its installation is so complex and its effects are so important, that ideally needed to be considered. Based on Coupled Eulerian-Lagrangian approach, this paper proposes a numerical approach to investigate the SCP installation effects. This
