强夯法处理大块石堆填土地基初探

On Backfill Foundation of Rock Blocks with Dynamic Compaction

本文结合某电厂采用强夯法加固干煤棚区大面积松散大块石堆填土地基的工程实例,针对强夯法处理大块石堆填土问题进行初探,分析结果证明强夯法处理大块石堆填土地基效果明显。另外对该类型地基提出了梅纳德(Ménard)修正公式的修正系数的建议值,在工程应用方面具有一定的参考意义。

In this paper,a power plant using dynamic compaction method to reinforce large area of loose rock blocks fill foundation engineering in the dry coal shed is taken as an examples,and make an analysis aiming at dynamic compaction for treatment of rock blocks fill foundation,whose results show that the effect of dynamic compaction for rock blocks backfill foundation is obvious.The other is that the recommended value of Ménard correction coefficient formula is put forward according to this type of foundation,which has a certain reference value in engineering applications.
