城市地铁暗挖区间监测成果及数据分析

Monitoring Data Analysis of Mining Section in Urban Metro Construction

以深圳地铁2个暗挖区间隧道工程为例,阐明如何利用监测成果分析不同开挖阶段的地面下沉和洞内结构的周边位移产生原因和发展规律,以便更好地完善修改设计。

The monitoring data analysis, as the last step of monitoring and measuring in the metro construction, is very important for understanding the deformation principles of ground surface and the structure during the metro excavation. By taking two mining sections of Shenzhen metro tunnel as examples, the method of how to analyze the reasons and principles of the ground settlement and the displacement of the tunnel structure in different stages are clarified, which can be used to modify the design, guide construction and ensure construction safety.
