本文介绍了石砭峪水库有两个弯道的高流速无压泄洪洞的体形研究．这种泄洪洞的体形设计．是重大的技术难题．我们采用双复曲线体形、人工掺气跌坎和通气孔及出口不对称收缩式窄缝挑坎等措施，解决了技术难题．经水工模型试验验证，洞内流态和掺气情况正常，消能防冲效果显著．
This paper introduces the body shape of high flow rate non-pressure discharge tunnel with two corners in Shiyangyu Reservoir. This flood hole shape design. Is a major technical problem. We adopt the double complex curve body shape, artificial aerated hiccups and vents and export asymmetric shrink narrow slit pick ridge and other measures to solve the technical problems. The hydraulic model tests show that the flow and aeration in the cave are normal, and the effect of energy dissipation and anti-scouring is remarkable.
