强夯处理饱和砂土液化

Dynamic compaction treatment liquefaction of saturated sand

结合中营高速公路K53＋600～K58＋200段工程概况，采用强夯法处理饱和砂土液化地基，介绍了强夯施工的相关参数，探讨了强夯施工工艺，并对强夯前、后的标准贯入及土工试验情况进行了分析，指出强夯法具有提高土的强度、改善砂土的振动液化条件和消除湿陷性等作用。

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.
