锅浪跷水电站大坝变形监测网复测及稳定性分析

Repeated Measurement and Stability Analysis of Dam Deformation Monitoring Network of GUolangqiao Hydropower Station

大坝变形监测网是大坝安全监测的坐标基准,包括垂直位移监测网和平面位移监测网。结合锅浪跷水电站大坝监测网复测工作和相关规范,阐述了一等监测网的外业观测、观测成果整理与计算、起算数据选取、约束平差以及监测网点的稳定性分析等问题,为同类项目提供参考。

Dam deformation monitoring network is the coordinate reference of dam safety monitoring.It contains vertical and horizontal displacement monitoring network.Combined with repeated measurement of dam monitoring network and relative specification of Guolangqiao hydropower station,this paper introduces the field observation,data reduction and calculation,initial data selection,constrained adjustment of first-class monitoring network,and stability analysis of monitoring network points discussed,which can provide a reference for similar projects.
