GNSS及测量机器人在水电站安全监测中的应用

Application of GNSS and Measurement Robot in the Safety Monitoring of Hydropower Station

随着水电工程建设的快速发展,大坝工程建设规模逐渐加大,大坝安全监测工作越来越重要,监测项目和监测点越来越多,测量工作量加大,传统的人工监测方式难以满足安全监测工作需要,无法实现实时监测和快速分析,因此,迫切需要实现大坝安全监测自动化。枕头坝一级水电站大坝所处地质结构极其复杂,且所处位置也极为重要,容不得任何事故出现。通过对枕头坝一级水电站大坝及边坡安全监测系统升级改造,采用GNSS及测量机器人变形监测系统,充分利用两者间的优点,并做到相互弥补,实现了对大坝安全的自动化及全天候监测,为大渡河流域已建电站的自动化升级改造提供了参考。

With the rapid development of hydropower engineering construction,the scale of dam engineering construction is gradually increasing,dam safety monitoring is becoming more and more important,monitoring items and monitoring points and the workload of measurement is increasing,the traditional manual monitoring method is difficult to meet the needs of safety monitoring work,and there is no way to achieve realtime monitoring and rapid analysis.Therefore,it is urgent to realize the automation of dam safety monitoring.The geological structure of Zhentou dam 1 hydropower station is very complex,and its location is also very important,so no accidents are allowed.Through upgrading the dam and slope safety monitoring system of 1 hydropower station of Zhentou dam,GNSS and deformation monitoring system of measuring robot are adopted to make full use of the advantages of the two and make up for each other,so as to realize the automatic and all-weather monitoring of dam safety,which provides a reference for the automatic upgrading of the existing power stations in Dadu River Basin.
