以成都地铁2号线一期工程土建23标段沙河堡站—站东广场站区间暗挖隧道工程为例,按照区间隧道施工监测设计要求,开展和加强监测工作,根据实时的变形数据,分析判断预测工程施工中周边环境及围护结构变形情况,采取有效措施,达到控制指导工程施工,保护周边环境及围护体系的目的,确保施工安全。
Taking the tunneling project of Shahepu Station - Station East Square Station in section 23 of the first phase of Chengdu Metro Line 2 as an example, the monitoring and control work was carried out and strengthened according to the monitoring design requirements for the tunnel construction in the interval. According to the real-time deformation data, Judge the prediction of the surrounding environment and the deformation of the envelope, and take effective measures to achieve the goal of controlling and guiding the construction of the project, protecting the surrounding environment and enveloping the system, and ensuring the construction safety.
