[摘要] 对CFG桩复合地基进行承载力检测时，承压板底面下垫层铺设方式及CFG桩浅部断裂对复合地基承载力有较大影响。从CFG桩加固地基机理、规范要求等方面人手，结合具体工程实例，得出了有意义的结论，为CFG桩复合地基承载力检测时提供参考。

Abstract:  When testing CFG piles composite foundation, the laying way of the cushion under bearing plate and the shallow fracture of CFG piles composite have significant impact on the bearing capacity of composite foundation. A meaningful conclusion was recevied from the mechanism of CFG piles foundation, specifications and other aspects, combined with specific examples of projects. It can provide references for similar projects.
