测量机器人在黄土地区地铁结构安全保护中的应用

以西安地铁2号线安全保护区内施工的南门广场改造提升项目及南门隧道工程为依托,对永宁门车站及钟楼站—永宁门区间隧道进行测量机器人自动化监测。通过对监测数据的分析,证明自动化监测具有较高的可靠性,可代替传统测量手段应用于地铁结构的安全监测。研究显示,受上覆土体开挖的影响,盾构隧道会出现隆起及竖椭圆受力变形。

Application of Measuring Robot in Safety Protection of Subway Structure in Loess Area

The upgrading project in the South Gate Plaza and the project of South Gate tunnel located in the safety protection area of Xi'an Subway Line 2 are studied.The automatic monitoring by the measuring robot is adopted for Yongningmen station and the sectional tunnel between the Zhonglou station and Yongningmen station.The analysis of the monitoring data proved that the automatic monitoring system with high reliability could replace the traditional means of measurement used for safety monitoring for subway structures.Research shows that the shield tunnel will uplift and has vertical elliptical deformation influenced by upper soil excavation.
