混凝土面板堆石坝渗流量影响因素和变化规律分析

Analysis of Affecting Factors and Regularity of Seepage Quantity of Concrete Face Rockfill Dams

总结了混凝土面板堆石坝渗流量的影响因素,介绍了渗流量观测资料的分析方法。采用年调节水库和抽水蓄能电站面板堆石坝的渗流量实测资料,分析了渗流量的变化规律和特征值,建立了统计模型和回归模型,定量地分析了各影响分量的影响效应,可为同类工程的渗流量分析和评价提供有益的借鉴。

The factors affecting the seepage quantity of concrete face rockfill dams are summarized, and the analysis methods for observation data of seepage quantity are introduced. Based on the observation data of seepage quantity obtained from the dam of a annual storage reservoir and that of a pumped storage power station, the regularities and characteristic values are analyzed, the statistical model and regression model are established, and the affecting components are calculated by quantitative analysis. The results are helpful to the analysis and evaluation of seepage quantity of similar dams.
