摘　　要：通过对南京某大厦深基坑支护结构侧土压力的实测研究 ,分析和研究了软土地区悬臂支护结构、单层支点混合支护结构、连拱支护结构侧土压力分布的基本规律。Based on the in situ measured data of certain deep foundation pit excavation in Nanjing city include earth pressure and lateral deformation of retaining structure.Magnitude and distribution of lateral earth pressure at different excavation depth supported by different retaining structures, such as cantilever retaining structure, single pivot mixed retaining structure and borehole cast in place concrete pile multi arch retaining structure are discussed in this paper.

关 键 词：深基坑 土压力 悬臂支护结构 单层支点混合支护结构 连拱支护结构
