摘　　要：水布垭水电站大坝为目前世界上已建成的最高混凝土面板堆石坝,其总渗漏量为大坝安全稳定运行的重要评价指标。根据水布垭大坝面板历次修补情况,从实测数据出发对比分析面板修补前后渗流量变化,采用统计模型分析了库水位、降雨量、温度、面板破损及修补等因素对总渗流量的影响规律,与同类工程对比,说明大坝面板的缺陷修补效果较好。Shuibuya Dam is the highest concrete face rockfill dam in the world.The total seepage flow through the dam is an important evaluation index of its operation safety and stability.According to the previous repair work of the face slabs,the variation of the measured total seepage flow before and after the repair of the face slabs is analyzed.Statistical models are adopted to study the influences of the reservoir water level,rainfall,temperature,slab damage condition and repair work on the total seepage flow.Compared with similar projects,the results show that the face slab repair work is of satisfactory effects.
