北斗自动化监测系统在市政路堑边坡的应用

Application of BeiDou Automated Monitoring System in Municipal Cut Slope

边坡失稳破坏预警一直以来都是工程界研究的重点,市政道路建设过程中对山体进行开挖,破坏了原有的应力场,形成的路堑边坡存在滑坡的安全隐患,严重威胁道路施工及后期公路运营安全。本文基于北斗卫星定位技术,建立北斗位移监测系统,对某市政公路路堑边坡进行施工期的自动化监测。通过建立四级预警机制,设置合理的预警值,对边坡进行了成功预警,确保了施工人员安全。研究结果可为市政路堑边坡的监测预警提供经验借鉴与参考。

Early warning of slope instability and failure has always been a key research focus in the engineering community.During the construction of municipal roads,excavation of mountains disrupts the original stress field,leading to the formation of cut slopes that pose a potential risk of landslides,seriously threatening the safety of road construction and subsequent highway operations.Based on BeiDou Satellite Navigation System technology,this paper establishes a BeiDou displacement monitoring system to conduct automated monitoring of a municipal highway cut slope during the construction period.By establishing a four-level early warning mechanism and setting reasonable warning thresholds,successful early warnings were issued for the slope,ensuring the safety of construction personnel.The research results can provide experience and references for the monitoring and early warning of municipal cut slopes.
