摘要
本文通过安全监控分析评估大坝安全运行状况,以便制订合理水库运行方案,确保坝高162 m的滩坑混凝土面板堆石坝初蓄期的安全运行。大坝变形监测使用TCA全站仪优化现场观测方案,采用极坐标法加大气垂直折光进行修正的EDM三角高程法自动观测大坝三维坐标,削弱大坝垂直折光的影响,满足规范规定的监测精度,快速高效地取得大坝变形监测资料。通过大坝表面、坝体内部变形及大坝渗流资料的分析,表明大坝初蓄期运行状态安全稳定,性态基本正常,安全监测方案先进科学。
Tankeng concrete face rockfill dam is 162meters high.Analyse and evaluate safety operation of Tankeng concrete panel dam through safety monitoring,institutes appropriate operation plan for initial impound period safety operation of dam.Used TCA Total Station by optimized project of monitoring,Adopted the polar coordinate method and EDM triangulation height adding atmosphere vertical refraction light corrected to monitor automatically three-dimensional coordinate,weakened effect of atmosphere vertical refraction light,satisfied monitor accuracy,obtained quickly and efficiently monitoring data.Pass monitoring data of dam surface and body attest that the dam operation is safety and stability,monitoring project is advanced and scientific.
