强夯法在碎石土高填方边坡中的应用

Application of Dynamic Compaction in High Slope Filled with Gravel Soil

针对某碎石土地基填土厚度大,土质松散,地基不均匀等特点,采用强夯法对地基进行处理。按照强夯处理的技术要求,并根据试夯结果确定了强夯参数。最后,通过载荷试验、动力触探、现场土工试验等手段检验了强夯法的处理效果。同时,通过强夯前后边坡稳定性的对比,分析了强夯对边坡稳定性的影响。该工程填土地基经强夯处理后,地基性状得到了明显改善。

Based on the characteristics gravel soil foundation filling in thickness, loose soil, nonuniformity, dynamic compaction is used. According to the technical requirements and the test results of dynamic compaction, the parameters of dynamic compaction are determined. Finally, this paper confirmed the treatment effect of dynamic compaction through load test, dynamic penetration, on - site soil tests, and so on. Meanwhile, the paper analysed the slope stability by the comparison of slope stability before and after the dynamic compaction. The ground behaviors of the fill foundation for the construction are improved after dynamic compaction
