摘要
根据锦屏二级水电站引水隧洞充排水的前期准备工作、方案选择、过程控制、风险分析及控制措施,利用不同阶段充排水特点,将高水头、长距离、大直径引水隧洞充排水工作分割成多个独立的充排水过程,可降低风险,提高充排水效率,已取得了很好的效果,积累了引水隧洞充排水经验。
The water filling and drainage process of the diversion tunnel in Jinping Ⅱ Hydropower Station is introduced, including the preparations, scheme selection, process control, risk analysis and control measures. As the diversion tun- nel is of high water head, long distance and big dimension, the whole filling and drainage process is carried out in differ- ent stages considering the different characteristics of each stage. Thus, the risk is reduced and the efficiency is im- proved. Satisfactory results are observed in the practice. It could be useful experience for the water filling and drainage of similar diversion tunnels.
