摘要
以某水电站面板砂砾石坝为例,根据地形地质条件,建立了三维有限元模型,分析了4种工况下坝址区渗流场、渗漏量、渗透坡降的变化特性,找出了渗漏量偏大的原因为左、右岸帷幕下方可能存在渗漏通道,并建议加强观测、及时进行分析。
Based on the topographic and geological conditions of a certain facing gravel dam, three-dimensional timte element model of the dam is established. And the variation characteristics of seepage filed, leakage and seepage slope of the dam site are analyzed under four operating conditions existed leakage passage below the left and right curtains. gested. Then the reason of the large leakage is found that there may be Finally, strengthening monitoring and timely analysis are sug-
