干振碎石桩加固软弱地基,使碎石桩与被挤密的土体共同组成复合地基,按变形一致的原则,由压缩性小的碎石桩承受大部分上部竖向荷载,桩间土承受部分荷载。复合地基土体在水平力作用下,产生径向位移,使碎石桩周围形成非常密实的挤密区,土反过 Dry vibration gravel pile to strengthen the soft foundation so that the gravel pile and the compacted soil together form a composite foundation, according to the principle of consistent deformation, from the small compressive gravel pile to withstand most of the vertical load, soil between the piles Bear part of the load. Under the action of horizontal force, the composite foundation soil produces radial displacement so that a very compact compaction zone is formed around the stone columns, and the soil is reversed
