摘要
对水布垭水利枢纽工程高水头大流量泄洪条件下,带有弯曲引水渠和差动窄缝挑坎的溢洪道水力特性进行了模型试验研究。观测了引水渠和溢洪道内的水流流速分布和流动形态,分析和评价了斜型差动窄缝挑坎挑流特性,初析了消能效果。
discharge Shuibuya A model experimental study is conducted on the hydraulic characteristics of the high head and large spillways with a curved inlead canal and five differential slotted flip bucket terminal structures for hydropower project. Flow pattern and flow velocity profile in the inlead canal and and measured, and as well as the jet flow behavlour is analyzed. Energy dissipation of the slotted flip bucket terminal structures is briefly discussed. spillways are observed spillways with stepped
