Abstract Liquefaction of foundation soil causes significant damage to infrastructures. The sand compaction pile (SCP) method is a countermeasure against liquefaction to densify the ground by installing dense sand piles. In recent years, an innovative method has been developed to install sand piles into the ground at any angle. In this study, a series of dynamic centrifuge tests are carried out to investigate the effects of the angle of the SCP improvement zone on mitigating the liquefaction-induced settlement of embankment crests. The lateral displacement beneath the embankment toes is mitigated by the presence of the improvement zone installed in the foundation ground. In particular, the case with a 50° improvement zone is the most effective in mitigating lateral displacement and contributes to the lower settlement of the embankment.
Highlights Lateral displacement beneath the embankment toes is mitigated by the improvement zone installed below the embankment toe. The case with inclined improvement zone shows better performance in mitigating lateral displacement and settlement of the embankment. The deformation pattern of the soil below the embankment toe is also important for the mitigation of crest settlement.
