针对目前在多孔河岸式溢洪道上采用窄缝挑坎消能工,都是沿闸墩用长墩隔开,至出口段将墩体升高加厚、急剧收缩成窄缝的结构形式。
6) curvature flip-bucket
扭曲挑坎
1.
This paper optimizes the flip-bucket of the tunnel by experiments,and the result indicates both curvature and slit-type flip-bucket can carry the flow into the downstream river well,and the maximum wave height and the scouring pit of biggest depth occur near the ridge;for the scheme of curvature flip-bucket,the scouring p.
针对以上特点,本文对深孔泄洪洞出口体型提出斜切扭曲挑坎和窄缝挑坎两个方案,并分别进行了优化试验研究,结果表明:斜切扭曲挑坎方案和窄缝挑坎方案的归槽情况都较好,涌浪最大的地方及冲坑最深点均在山嘴处;斜切扭曲挑坎方案的冲坑较浅,但涌浪高且电站尾水处可能有泥沙进入;窄缝挑坎方案对电站尾水影响小,但冲坑深度较斜切扭曲挑坎方案大。
