赛格水电站具有低水头、大单宽流量、低佛汝德数等特点,泄洪消能问题突出,通过水工模型试验研究,提出了采用Y型宽尾墩跌坎消力池联合消能方式。
2.
The dispatching principle of the outlet sluice of low water head junction is analyzed and determined and the dispatching control conditions of the outlet sluice of Zhuzhou navigation power junction located in the branching channel are put forward.
分析确定了低水头枢纽泄水闸调度原则,提出了位于分汊河道的株洲航电枢纽泄水闸调度控制条件,通过整体模型试验研究,在保证枢纽泄水闸消能安全、满足船闸通航水流条件、提高枢纽电站效益的情况下,确定了枢纽泄水闸的优化调度方案。
3.
Through a model test for Qihe river inverted siphon system, aeration problem and air hole place for a low water head and great flow rate inverted siphon system were studied.
通过南水北调中线工程淇河渠道倒虹吸模型试验 ,对低水头大流量倒虹吸进口掺气及通气孔设置问题进行了研究 ,结果表明 :无论控制闸宜设在上游或下游 ,不存在进口水跃问题 ,上游设闸控制虽有掺气问题 ,但是量小无害 ,因此 ,低水头大流量倒虹吸管进口不需要设置通气孔。
2) low head
低水头
1.
