引水建筑物在引水式电站中所占投资比例较大,发电引水隧洞是引水式电站较为简单和常用的引水建筑物,因而发电引水隧洞型式选择对引水建筑物乃至工程布置、工程投资及效益影响较大。文章分析了发电引水隧洞压力状态对引水建筑物和工程布置的影响。
Water diversion structures account for a large proportion of investment in diversion hydropower stations. Power generation diversion tunnels are relatively simple and commonly used diversion structures for water diversion hydropower stations. Therefore, the choice of power generation diversion tunnels has a significant impact on diversion structures and project layout, project investment and benefits Larger. The paper analyzes the influence of pressure status of diversion tunnel on diversion structures and engineering layout.
