东风水电站防渗帷幕优化

Optimization of Impervious Curtain of Dongfeng Hydropower Station

东风水电站岩溶发育,在工程设计中较全面地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;在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了大幅度的优化,经10多年水库运行结果表明,东风水电站帷幕防渗效果良好,这为岩溶地区筑坝的防渗优化处理提出了新的思路。

The karst is developed in Dongfeng hydropower station In the process of the project, the basic regular of karst development is more overall mastered, and the project geology and hydrogeology conditions are analyzed. Design in The antiseepage path, structural layout, construction technique and materials are optimized by a big margin optimization. The reservoir operation for 10 years shows that the impervious curtain of Dongfeng hydropower station is effective. It proposes new idea of imperious treatment of dam construction in the karat area.
