摘　　要：本文以实际工程为研究对象,对CFG桩施工过程中的检测方法及结果和后续施工阶段桩身沉降变形规律进行了深入分析。首先总结了适用于建筑桩基础的各项检测方法,并对研究对象所进行的桩基检测结果进行分析,结果表明CFG桩施工质量满足设计要求。在此基础上,对基坑沉降量随时间变化规律进行分析,发现了桩基沉降曲线存在沉降平台期、沉降异常点等情况。综合分析发现地下水波动会对桩基沉降量产生明显的规律性影响。因此,本文为建筑桩基础应力变形规律的研究提供了一定程度上的理论支持。In this paper,the actual project is taken as the research object,and the detection methods and results in the construction process of CFG pile and the settlement deformation law of pile body in the subsequent construction stage are analyzed in depth.Firstly,the summarizes the detection methods suitable for building pile foundation,and analyzes the pile foundation detection results of the research object,the results show that the construction quality of CFG pile meets the design requirements.On this basis,the variation law of foundation pit settlement with time is analyzed,and it is found that the settlement curve of pile foundation has settlement platform period and settlement anomaly point.The comprehensive analysis shows that the fluctuation of groundwater will have obvious regular influence on the settlement of pile foundation.Therefore,this paper provides theoretical support for the study of stress deformation of building pile foundation to a certain extent.
