挤密碎石桩上部加固作用不如强夯，关于丰满和软土，结合挤密碎石桩加强夯施工，加固作用会十分显着。挤密碎石桩既可起侧向挤密作用又可起竖向排水作用。
The strengthening effect of the upper part of compacted gravel pile is not as good as that of dynamic compaction. As for the plump and soft soil, the strengthening effect of compacted gravel pile combined with the strengthening construction of compacted gravel pile will be very significant. The compacted gravel pile can not only compact laterally but also drain vertically.
挤密碎石桩加强夯比单纯挤密碎石桩布桩少，工艺可简化，而其总费用与单纯挤密碎石桩计划比较根本相等或只略高一点，且加固后可满意一般修建、工业厂房、设备根底的承载力和变形要求。
Compaction of compacted gravel pile is less than that of simply compacted gravel pile cloth pile, and the technology can be simplified. The total cost of compacted gravel pile is basically the same or only slightly higher than that of simple compacted gravel pile plan, and the consolidation can satisfy the bearing capacity and deformation requirements of general construction, industrial plant and equipment foundation.
