摘　　要：分析CFG桩的加固机理和竖向的应力传递特征。通过一个工程实例,验证了CFG桩的设计计算思路,分析弦线模量法和复合模量法在计算沉降方面的利弊,并与实测沉降进行对比分析,发现弦线模量法比较适合关中地区CFG桩复合地基的设计计算,具有推广价值。In the analysis ofthe reinforcement mechanism and the vertical stress transfer characteristics of CFG pile,the calculation ideas about CFG pile design is verified in the case of project,compared with the actual calculation of settlement,the advantages and disadvantages of calculation of the settlemen by strings modulus method and composite modulus method are analysed.It is discovered that strings modulus method is suitable for the calculation design of CFG pile composite foundation in the Guanzhong region and has promotional value.
