Mechanism and application of impact compaction in foundation stabilization of hydraulic reclaimed silty fine sand ground

Based on the theory of sandy soil liquefaction,the working principle of impact compaction on silty fine sand ground was analyzed and the mechanics was put forward.An industrial trial was carried out on silty fine sand ground in Caofeidian District of Shougang Group,and the results and effects indicate that it is absolutely feasible to use this technology in this kind of situation.
