江坪河水电站水库下闸蓄水方案研究

Research on Reservoir Impoundment of Jiangpinghe Hydropower Station

江坪河水电站大坝是目前建造的世界第三高混凝土面板堆石坝,水库库容大,蓄水历时长,导流洞封堵施工及大坝安全等对蓄水进程控制要求高。在确保工程安全的前提下,充分考虑并分析工程形象面貌、蓄水位控制、下游生态、初期发电等因素,提出了水库下闸蓄水方案,方案的研究思路和方法对类似工程具有一定借鉴意义。

The dam of the Jiangpinghe Hydropower Station is currently the world’s third-highest concrete faced rockfill dam.Because the reservoir has a large storage capacity, the impoundment of reservoir will need a long time, and the diversion tunnel plugging construction and dam safety also need a strict control on water storage process. On the premise of ensuring the safety of project, the factors of the appearance requirements of dam construction, water level control, water demand of ecology in downstream areas and initial power generation are fully considered and analyzed, and then a reservoir impoundment scheme is proposed. The research ideas and methods of the water impoundment scheme of this project will have certain references for similar projects.
