摘要
根据河段的水能资源特点,修建控制性的水利枢纽工程。介绍了枢纽工程中长发电隧洞的洞径计算方法,通过洞径、水头损失、多年平均发电量、工程量、投资及经济净现值的比选分析,论述了长距离发电隧洞洞径的选取对发电效益和工程投资的影响。
The controlled hydro-junction project was constructed according to the hydropower resources characteristics of reach. In this paper, the calculation method for long distance power tunnel diameter of hydro-junction project was introduced. Through the comparison and the analysis on tunnel diameter, head loss, multi-year average generating capacity, engineering quantity, investment and economic net present value, the influence of long distance power tunnel diameter selection on generating benefit and project investment was discussed.
