叶巴滩水电站截流规划设计

Planing and Design of River Closure in Yebatan Hydropower Station

叶巴滩水电站位于金沙江干流上游,系金沙江上游13个梯级水电站的第7级。电站采用坝式开发,双曲拱坝,最大坝高217.0m,电站总装机容量为2285MW。在研究了截流时段、截流标准、截流方式、截流方案及截流布置的基础上,分析了河床截流难度,推荐了单戗堤、单向立堵进占得截流规划设计方案。

Yebatan station is located on the upper reaches of the main Jinsha River,the seventh level of13 casecade power stations on the upstream of the Jinsha River,and the power station belongs to dam type development,double curvature arch dam with the maxmum dam height of 217. 0 meters and total installed capacity of power station of 2285 MW. Based on the study on closure time,standard,way,scheme and layout in the paper,by analyzing the difficulty of river-bed closure,the scheme of single berm and one-way closure planning and design is recommoned.
