摘要
瀑布沟水电站枢纽工程由拦河大坝、溢洪道、泄洪洞、放空洞、引水发电及尼日河引水等主要建筑物组成。枢纽布置经设计优化采用左岸地下厂房长尾水方案,即河床中建砾石土心墙堆石坝,左岸布置引水发电建筑物及泄洪建筑物,右岸设置1条放空洞。尼日河引水入库工程在开建桥建闸,左岸布置引水隧洞,隧洞出口布置在大渡河右岸距坝轴线上游约0.9 km处。现工程已建成,运行情况良好。
The hydraulic structures of Pubugou Hydropower Station are consisted of dam, spillway, discharge tunnel, emptying tunnel, diversion system for power generation and diversion system from Niri River. The conceptual design of project layout with left bank underground powerhouse and long tail water was selected after optimization. The gravel soil core rockfill dam locates on the riverbed, diversion system for power generation and flood discharge structures locate on the left bank, and the emptying tunnel locates on the right bank. Niri River diversion system includes a lock dam in Kaijianqiao and a diversion tunnel in the left bank of Niri River. The outlet of Niri River diversion tunnel is arranged in the right bank of the Dadu River and 0.9 km upstream to Pubugou dam axis.
