纪村大坝坝顶垂直位移监测资料分析

Analysis on Vertical Displacement Monitoring Data of Jicun Dam Crest

根据水工建筑物安全监控理论,运用逐步回归分析方法建立了纪村大坝坝顶垂直位移的统计模型,对监测资料进行了定性和定量分析,揭示了该电站坝顶垂直位移的变化规律,并利用统计模型提取了典型年份水压分量、温度分量和时效分量在大坝垂直位移中所占的比例,为分析大坝的运行状态提供了依据。

According to safety monitoring theory of hydraulic structures, this paper establishes the statistical model of vertical displacement for the Jicun dam crest by Stepwise Regression Analysis Method. It conducts a qualitative and quantitative analysis on the monitoring data, reveals the change law of vertical displacement of the dam crest, and determines the proportion of the hydraulic pressure component, temperature component and aging component during the typical years in the vertical displacement based on statistical model, providing evi- dence for analyzing running state of the dam.
