橡胶坝和WES堰下泄水流脉动压强研究
|
摘要
通过试验,对橡胶坝与WES堰在不同的消力池长度、不同的消力池尾坎高度、不同的流量工况下下泄水流的脉动压强进行分析,研究橡胶坝与WES堰下泄水流与上游来水流量及下游消力池状况的关系。结果表明:随着流量的增大,橡胶坝与WES堰脉动压强时均值增大,但橡胶坝相对WES堰脉动压强波动较大;橡胶坝与WES堰的脉动压强最大值都发生在消力池的尾坎。
Through the comparison of rubber dam and WES weir in different lengths of stilling basin,different stilling basin tail heights anddifferent traffic scenarios,the fluctuating pressure on their discharge flow data was measured and analyzed. It studied the relationship betweenthe rubber dam and WES weir discharge flow,upstream and downstream water and the stilling basin. Results show that as the flow increases,the pulsation pressure of the rubber dam and WES also increase,but relatively rubber dam and WES weir pulsation pressure value fluctuatesgreatly;the fluctuates of the rubber dam is greater than that of the WES weir;their maximum fluctuation pressures all occur in the tail of thestilling basin.
