| Abstract: | 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. |
