二滩水电站大坝水平位移基准网及校核网系统稳定分析

Analysis on the Stability of Horizontal Displacement Monitoring Reference Network and Calibration Network System for the Dam of Ertan Hydropower Station

基于二滩水电站定检过程中监测系统评价的相关技术要求,通过对大坝水平位移基准网及校核网的现场检查、精度分析和网点的稳定性分析,给出了基准网稳定性的评价意见并提出了应结合多种监测技术手段对基准网的计算平差进行优化的建议,以提高基准网的稳定性。

Based on relevant technical requirements for evaluation of monitoring system in the process of regular inspection of Ertan Hydropower Station,evaluation on stability of the reference network is given in this paper through on-site inspection,accuracy analysis and network stability analysis on the horizontal displacement reference network and calibration network for the dam.Optimization of the calculation adjustment of the reference network is suggested to be done with a variety of monitoring techniques,so as to improve the stability of the reference network.
