碎石桩+垫层强夯在机场填方地基处理中的应用

Application of gravel pile + cushion compaction in airport embankment foundation treatment

针对地基土承载力不足和填筑体产生较大的沉降问题,提出采用碎石桩与强夯法联合进行施工处理的方法,处理后的软土地基能达到要求的地基承载力,同时减少了沉降。实践证明,联合作业具有一定的优越性,值得推广。

In light of foundation bearing capacity shortage and embankment settlement and other problems, the paper adopts united construction treatment method of gravel pile ＋ cushion compaction. As a result, the soft soil foundation processed can meet the foundation bearing capacity and reduce settlement. Practice proves that： the united operation has certain superiority and is worth promoting.
