摘要
通过对锦屏一级水电站运行期跨江段谷幅历年变形值进行比较分析,总结运行期谷幅的变形规律和左岸边坡的变形收敛情况;采用逐步回归分析方法,分析运行期边坡谷幅变形的影响因素,分析库岸岩体变形与库水位、气温及其他作用因子的相关性,总结运行期左岸变形的时空分布规律与特点;通过各种观测手段与谷幅变形进行对比分析,对谷幅观测的可靠性进行验证,论证谷幅成果的可靠性和真实性。
By comparing and analyzing the historical deformation values of valley width of Jinping I Hydropower Station during the operation period,the deformation laws of valley width and the deformation convergence of left bank slope during the operation period are summarized.The stepwise regression analysis method is used to analyze the influencing factors of slope valley deformation during operation period,and the correlation between reservoir bank rock mass deformation and reservoir water level,temperature and other factors.The temporal and spatial distribution rules and characteristics of left bank deformation during operation period are summarized.By comparing the valley width deformation data with the monitoring data of various observation methods,the reliability of valley width observation is verified and the reliability and authenticity of valley width deformation results are demonstrated.
