第四系松散土层强夯施工试验研究

The Quaternary Loose Soil Dynamic Compaction Construction Testing

以江西地区某工程第四系松散土层的地基强夯处理为背景,对强夯施工中夯沉量、深层土层水平位移、孔隙水压力及地下水等情况进行了监测并通过室内土工试验、平板荷载试验及标准贯入试验对该地基的强夯处理进行了检测。结果表明:该工程地基采用强夯处理后,加固效果明显,地基承载力大幅提高。

Taking the dynamic compaction treatment of quaternary loose soil of a project in Jiangxi area as the background, the compaction settlement, horizontal displacement of deep soil, pore water pressure and groundwater were monitored, and through indoor soil test, plate loading test and standard penetration test on the foundation, the dynamic compaction treatment were detected. The results show that after it is treated by dynamic compaction, the effect is obvious and the bearing capacity of foundation is greatly improved.
