软土地区地铁车站深基坑邻近建筑物环境风险控制措施研究

Research on Environmental Risk Control Measures for Subway Station Deep Foundation Pit Adjacent Buildings in Soft Soil Regions

以某软土地区地铁车站深基坑工程为例,介绍了设计及施工中针对深基坑邻近建筑物环境风险所采取的风险控制措施,如加强基坑围护结构刚度,减小基坑侧壁变形;加强基坑工程地下水控制措施;采取槽壁加固措施;进行基坑开挖过程控制等,并通过监测数据验证了所采取的风险控制措施合理可靠。

Taking the deep foundation pit project of a subway station in a soft soil area as an example,the risk control measures taken in the design and construction are introduced,such as strengthening the stiffness of foundation pit envelope and reducing the deformation of foundation pit side wall;Strengthening groundwater control measures for foundation pit engineering;Taking measures to strengthen the groove wall;The process control of foundation pit excavation is carried out,and the monitoring data verify that the risk control measures taken are reasonableandreliable.
