［摘要］结合工程实例，对CFG复合地基承载力、变形和稳定性进行系统计算，将计算结果与现场检测结果进行对比，二者均满足规范要求，论证了CFG复合地基在黄河冲积平原地区高层建筑应用的可行性。分析得出，基础底面无软土层时CFG复合地基可不进行稳定计算。研究成果为CFG复合地基在该地区成熟应用提供科学依据和理论支撑。

Abstract:The systematic calculations of bearing capacity, deformation and stability of CFG (Cement Fly-Ash Gravel) composite foundation were carried out combined with the actual engineering. Comparison of the calculation results with field test ones shows that both of them can meet the requirements of code and the feasibility of applying CFG composite foundation in high-rise buildings in the Yellow River alluvial plain area is verified. Analysis shows that stability calculation is not needed for CFG composite foundation when no soft substratum is in foundation bottom. The study achievements can provide the scientific basis and theoretical support for the mature application of the CFG composite foundation in the Yellow River alluvial plain area.

Keywords:high-rise building; CFG composite foundation; bearing capacity of foundation; deformation; stability
