以天津滨海新区某交通枢纽明挖深基坑为例,对施工过程中地下连续墙的变形、混凝土支撑轴力、坑外地下水位和地面沉降的变化进行了监测。基于监测数据进行了相应的变化规律和原因分析,所获得的结论对软土地区类似深基坑工程的施工监测具有参考借鉴意义。 Taking the deep excavation of open pit at a transportation hub in Tianjin Binhai New Area as an example, the deformation of continuous diaphragm wall, the axial force of concrete support, the water table outside the pit and the settlement of the ground during the construction process were monitored. Based on the monitoring data, the corresponding variation rules and reasons are analyzed. The conclusions obtained are of reference significance to the construction monitoring of similar deep foundation pit projects in soft soil areas.
