盖下坝水电站厂房尾水优化设计

Optimal Design on the Tailrace Canal of Gaixiaba Hydropower Station

对盖下坝水电站厂房尾水渠交叉建筑物结构两种形式进行了比选分析,结果认为,尾水渠与厂房下游曲溪河立体交叉,采取长尾水洞形式从下部穿越曲溪河,充分利用了水能资源、增加了发电量,不仅保证了结构的安全性,方便了施工,也节省了工程投资,降低了施工难度,为今后类似工程提供了设计新思路、新方法。

Two cross stnactures for the tail water of Gaixiaba Hydropower Station and the downstream Quxi River were compared and the flyover crossing was selected. Taking tunnels through Quxi River from the bottom can fully utilize the hydro resources, ensure the safety of the structure, facilitate the construction and save investment. The practice provides a new idea and method for similar project design in the future.
