106 Liquefaction Mitigation of Ground Treated with Granular Piles: Densification Effect. compaction piles (SCPs) but the increase depends on the fines content (Figure 1). Densification by RGP causes increase in deformation moduli and decrease in the coefficients of permeability and volume change.
Sand Compaction Pile (SCP) Method, developed in Japan in 1950 and widely used in Japan and Korea, is the right solution. SCP is one of the methods to strengthen the soft ground and to obviate or reduce the dredging for seawall construction. Typical section of quay wall supported by SCP.
