摘要
本文利用模型试验的方法,对采用施工导流隧洞代替地下力水电站的尾水隧洞,进行非恒定流的试验研究。通过各种方案的试验得出:当水电站负荷变化时,尾水隧洞内会发生明满流交替,其负压可采用设置通气孔的方法来减小。研究证明,明满流交替对水电站的稳定运行没有不良影响。
In this paper a model test is reported about the research of unsteady flow within the tailrace tunncl of an underground hydropower station. The construction diversion tunnel is adopted for substituting the tailrace tunnel of the station. This research provides the foundation to prove its feasibility and show its evident economic benefit.
