With the completion of a large number of major water conservancy projects with the characteristics of "high water head, large flow, and complex geological conditions", the environmental problems caused by flood discharge atomization have become increasingly prominent, and it is urgent to carry out research on mitigation technology of flood discharge atomization. The types of flip bucket have a direct impact on flood discharge atomization. Based on the methods of physical model test and numerical simulation calculation, the influence of flip bucket types on flood discharge atomization is studied. The results show that: under the same test conditions, the distribution of the nappe wind velocity of the continuous bucket is symmetrical along the two sides of the downstream axis, showing a unimodal distribution; and the distribution of the nappe wind velocity of the contraction bucket and the expansion bucket is approximately symmetrical bimodal distribution. The distribution of flood discharge rainfall is closely related to the type of the flip bucket. Compared with the continuous bucket, the number of the splashed water droplets of contraction bucket and expansion bucket is greatly increased. In the actual project, the purpose of reducing the influence of flood discharge atomization can be achieved by reasonably optimizing the types of flip bucket.

随着一大批具有“高水头、大流量、地质条件复杂”特点的重大水利工程建成,泄洪雾化诱发的环境问题日益突出,亟待开展泄洪雾化缓解技术研究。挑坎体形对泄洪雾化具有直接影响,为此应用水工模型试验和数学模型计算相结合的方法,研究了不同挑坎体形对泄洪雾化特性的影响。结果表明,相同条件下,连续坎的水舌风风速值沿下游河道轴线两侧对称并呈单峰分布,窄缝坎和扩散坎的水舌风风速值近似呈对称双峰分布;泄洪降雨分布与挑坎体形密切相关,较连续坎、窄缝坎、扩散坎的溅水量大大增加。因此,在实际工程中可通过合理优化挑坎体形,以达到减轻泄洪雾化的目的。

随着一大批具有“高水头、大流量、地质条件复杂”特点的重大水利工程建成,泄洪雾化诱发的环境问题日益突出,亟待开展泄洪雾化缓解技术研究。挑坎体形对泄洪雾化具有直接影响,为此应用水工模型试验和数学模型计算相结合的方法,研究了不同挑坎体形对泄洪雾化特性的影响。结果表明,相同条件下,连续坎的水舌风风速值沿下游河道轴线两侧对称并呈单峰分布,窄缝坎和扩散坎的水舌风风速值近似呈对称双峰分布;泄洪降雨分布与挑坎体形密切相关,较连续坎、窄缝坎、扩散坎的溅水量大大增加。因此,在实际工程中可通过合理优化挑坎体形,以达到减轻泄洪雾化的目的。

With the completion of a large number of major water conservancy projects with the characteristics of "high water head, large flow, and complex geological conditions", the environmental problems caused by flood discharge atomization have become increasingly prominent, and it is urgent to carry out research on mitigation technology of flood discharge atomization. The types of flip bucket have a direct impact on flood discharge atomization. Based on the methods of physical model test and numerical simulation calculation, the influence of flip bucket types on flood discharge atomization is studied. The results show that: under the same test conditions, the distribution of the nappe wind velocity of the continuous bucket is symmetrical along the two sides of the downstream axis, showing a unimodal distribution; and the distribution of the nappe wind velocity of the contraction bucket and the expansion bucket is approximately symmetrical bimodal distribution. The distribution of flood discharge rainfall is closely related to the type of the flip bucket. Compared with the continuous bucket, the number of the splashed water droplets of contraction bucket and expansion bucket is greatly increased. In the actual project, the purpose of reducing the influence of flood discharge atomization can be achieved by reasonably optimizing the types of flip bucket.
