Abstract

Shaking table tests were performed to investigate the response of liquefaction mitigation of rammed aggregate piers(RAP) on soft ground. The displacements of the soft ground reinforced by RAP under area replacement ratio 7, 14, 28% during seismic loading were measured. The result of tests showed that effects of liquefaction mitigation were affected various area replacement ratios and ground acceleration on RAP systems.
