CFG桩和碎石桩复合处理液化土层的设计与施工

Design and Construction of Combined Treatment with CFG Pile and Gravel Pile in Liquefying Formation

采用CFG桩和碎石桩相结合的复合地基方法处理黄河冲积平原新近沉积液化粉土地层,CFG桩属刚性桩,主要提高地基承载力,碎石桩则主要消除粉土层液化问题,通过该工程设计及实践,该复合地基方法处理黄河冲积平原液化地层的方法是可行的。

Composite foundation with CFG pile and gravel pile is taken in recently deposited liquefying silt ground in Yellow River alluvial plain. CFG pile can increase the bearing capacity of foundation with its rigidity, and gravel pile can eliminate the liquidation of silt ground. This construction method is proved workable.
