Dynamic compaction treatment liquefaction of saturated sand

Zhang Shu-hon

Abstract

Dynamic compaction method was used to treat liquefaction subgrade of saturated sand combining with engineering situation in Zhongying highway K53+600～K58+200 section,the relative parameters of dynamic compaction construction were introduced,dynamic compaction construction technology was discussed,and analyzed standard penetration before and after dynamic compaction and soil testing situation,and point out that dynamic compaction method has improving soil strength,vibrating liquefaction condition of sandy soil and eliminating collapsibility effect.
