强夯法加固新近吹填土软弱地基

Reinforcement of soft foundation by dynamic compaction method

针对某工程新近吹填土高压缩性、高含水量、高灵敏度、低承载力等特点,进行了强夯法处理,并通过静载荷试验、静力触探试验及标准贯入试验,对地基加固效果进行了检验,结果表明地基土平均比贯入阻力及地基承载力均有大幅度提高,地基处理深度均大于4 m,处理后地基承载力特征值满足设计要求,并消除了表层土地震液化的可能性。

The project for the newly dredger fill,high compressibility,high water content,high sensitivity,low bearing force characteristic and the dynamic compaction method to deal with,static loading test,static cone penetration test and standard penetration test to examine the effect of foundation reinforcement. The results showed that soil average penetration resistance and foundation bearing force have been greatly improved,depth of foundation treatment were higher than 4 m,treatment foundation bearing force characteristic value to meet the design requirements and dynamic consolidation method eliminates the surface soil seismic liquefaction possibility eliminates the surface soil seismic liquefaction possibility.
