摘    要:小浪底大坝是枢纽安全监测的重要部位,埋设了大量内部观测仪器,布设了8条视准线。大坝外部变形监测方法采用了多测站边角交会和直接水准法、低测量机器人观测法、GPS卫星定位技术等。通过近几年的观测,取得了大量可靠的数据,为大坝安全运行提供了重要依据。从多年观测结果看,大坝垂直位移变化、水平位移变化均符合土石坝变形的一般规律。

关 键 词:变形观测 资料分析 大坝 小浪底水利枢纽

Abstract:The dam is important for the safety monitoring of Xiaolangdi Multipurpose Dam Project because a lot of instruments and 8 collimating lines have been built inside the dam. The methods of multi-measuring stations side angular intersection, direct leveling, Total Station Classical Automatic Target Recognition and GPS (Global Positioning System) etc. are adopted for monitoring the dam outer deformation. The results of the dam monitoring for years showed that the changes of vertical and horizontal displacements of the dam are in conformity with general regularity of earth-rock dam deformation.
Keywords:outer deformation observation  data analysis  dam  Xiaolangdi Multipurpose Project
