［摘要］結合工程實例，對CFG復合地基承載力、變形和穩(wěn)定性進行系統(tǒng)計算，將計算結果與現(xiàn)場檢測結果進行對比，二者均滿足規(guī)范要求，論證了CFG復合地基在黃河沖積平原地區(qū)高層建筑應用的可行性。分析得出，基礎底面無軟土層時CFG復合地基可不進行穩(wěn)定計算。研究成果為CFG復合地基在該地區(qū)成熟應用提供科學依據(jù)和理論支撐。

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
