[摘要] 對(duì)CFG樁復(fù)合地基進(jìn)行承載力檢測(cè)時(shí)，承壓板底面下墊層鋪設(shè)方式及CFG樁淺部斷裂對(duì)復(fù)合地基承載力有較大影響。從CFG樁加固地基機(jī)理、規(guī)范要求等方面人手，結(jié)合具體工程實(shí)例，得出了有意義的結(jié)論，為CFG樁復(fù)合地基承載力檢測(cè)時(shí)提供參考。

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.
Keywords: CFG piles composite foundation; test; cushion; shallow fracture
