近接施工对既有轨道交通工程影响监控与分析

Monitoring and Analysis of the Impact of Proximity Construction on Existing Rail Transit Projects

针对“邦泰集团南宁市青秀区民族大道以北高坡岭路以东GC2024-011地块”项目,采用自动化与人工复核监测相结合的方法,开展了接近施工对既有轨道交通工程影响的监控和分析。其中,自动化监测涵盖地铁隧道结构、轨道结构的竖向及水平位移、隧道结构净空收敛等内容;人工复核仅监测了轨道结构竖向位移监测。与此同时,还开展了隧道内基于计算机视觉的位移遥测技术同步监测,并进行了数据比对。此次监测方案的顺利实施取得圆满成功,为后续近接施工对既有轨道交通工程影响的研究提供了有效的现场布测方法和基础数据。

For the project of"Bangtai Group Nanning City Qingxiu District Nationality Avenue North Gaopoling Road East GC2024-011 Site",the monitoring and analysis of the impact of proximity construction on the existing rail transit project was carried out by combining the method of automation and manual review monitoring.Among them,automated monitoring covers the subway tunnel structure,vertical and horizontal displacement of track structure,tunnel structure clearance convergence and other related content.The manual review only monitored the vertical displacement of the track structure.At the same time,synchronous monitoring of displacement telemetry technology based on computer vision was also carried out in the tunnel,and data comparison was conducted.The smooth implementation of this monitoring plan has achieved complete success,providing effective on-site measurement methods and basic data for the study of the impact of adjacent construction on existing rail transit projects in the future.
