高层建筑CFG桩复合地基变形研究

Study on Deformation of CFG Pile Composite Foundation of High-rise Buildings

采用三本不同规范推荐的方法对西安地区某一高层建筑CFG桩复合地基变形进行了计算,并通过对计算值与实测值的对比分析,探讨了不同计算方法的适用性和沉降计算经验系数的合理取值,提出了该地区高层建筑采用CFG桩复合地基的适宜性,建议了适用于前期设计阶段的变形计算方法。

The CFG pile composite foundation deformation of a high-rise building is calculated by three recommends methods form three diferent code in Xi'an, and through the contrastive analysis of the calculated values and measured values, the applicability of different calculation methods and the reasonable values of settlement calculation experience coefficient were discussed, put forward the suitability of the CFG pile composite foundation in the high-rise buildings of the region, the deformation calculation method is proposed to the pre-design stage.
