摘要
以苏州狮山广场博物馆基坑工程为例,研究分析大面积深基坑开挖引起的围护结构变形及对周边轨道交通隧道的影响。分析结果表明:当靠近轨道交通一侧采用地下连续墙作为围护结构,同时对该侧坑底土进行加固处理,基坑围护结构及周边轨道交通隧道变形均可满足控制要求,从而验证工程设计中相关措施的有效性。分析成果也可为类似邻近轨道交通隧道的大面积深基坑工程的设计与施工提供参考。
Taking the foundation pit project of Shishan Square Museum in Suzhou as an example,the deformation of retaining structure caused by large-area deep foundation pit excavation and its impact on surrounding rail transit tunnels are studied&analyzed.The analysis results show that when the diaphragm wall is used as the retaining structure near the rail transit side and the subsoil of the side pit is reinforced,the deformation of the foundation pit retaining structure and the surrounding rail transit tunnel can meet the control requirements,so as to verify the effectiveness of relevant measures in the engineering design.The analysis results can also provide reference for the design and construction of large-area deep foundation pit engineering adjacent to rail transit tunnel.
