Abstract
Dynamic numerical analyses were performed to investigate the response of liquefaction remediation of rammed aggregate piers(RAP) on soft ground under free strain conditions. The safe factors of the soft ground reinforced by RAP during seismic loading of magnitude 6.5 were calculated. The results of simulation showed that factors of safety were affected various area replacement ratios, surcharge loads and depth of RAP systems.
