摘　　要：介绍了佛山石湾一个深基坑工程的设计实例。该工程设两层地下室,基坑深5.95～10.25 m,采用钻孔灌注桩作为挡土结构,坑内设置两道钢筋混凝土内支撑。通过对支护方案的选择和计算结果的分析,表明钢筋混凝土支撑体系稳定性好、变形小,基坑支护设计方案是合理的,满足规范要求。This paper introduces a design case of deep foundation pit engineering for Shiwan in Foshan. The project has the two-story basement with a foundation pit by 5.95~10.25 m deep. The cast-in-site pile is used as the retaining structure. There are two reinforced concrete inner supports in the pit. The selection of support scheme and the analysis of calculation result show that the reinforced concrete support system has the good stability and little deformation. The support design scheme of foundation pit is reasonable and can meet the code requirements.
