东风水电站防渗帷幕优化

Optimization of impervious curtain of Dongfeng hydropower station

乌江东风水电站岩溶发育，工程设计掌握岩溶发育基本规律，认真分析工程地质条件和水文地质条件，防渗处理设计中对防渗线路、结构布置、施工工艺和材料等进行大幅度的优化，十多年水库运行结果表明，东风帷幕防渗效果良好，这为岩溶地区筑坝的防渗处理提出了优化的思路。

The karst is developed in Dongfeng hydropower station. In the process of the project design, the basic regular of karst development is mastered, and the project geology and hydrogeology conditions are analyzed. Design inThe anti - seepage path, structural layout, construction technique and materials are optimized by a The beg margin reservoir operation for over 10 years shows that the impervious curtain of Dongfeng hydropower station is effective. It proposes optimal idea of imperrious treatment of dam construction in the karst area.
