独立基础下CFG桩复合地基承载力取值

摘要

通过对现行JGJ 79-2012《建筑地基处理技术规范》中CFG桩复合地基承载力设计方法进行探讨和分析,指出对独立基础下CFG桩复合地基承载力计算存在的问题,给出其相对合理的计算方法,并提出相应的合理检验要求,为广大的结构设计工程师提供设计参考.%In this paper,the current bearing capacity design method of CFG-pile composite foundation in the existing JGJ 79-2012" Technical Code for Ground Treatment of Building" is discussed and analyzed,and the problems in the calculation of bearing capacity of CFG-pile composite foundation under independent foundation are pointed out.Its relatively reasonable calculation method and the test-requirement are given in the paper,which gives design reference to the structural design engineers.
