电站溢洪道非对称进口导流墙体型优化研究

Study on the Shape Optimization of Asymmetric Inlet Diversion Wall of Spillway of Power Station

溢洪道是水利工程领域的首要泄水建筑物,对维护水利工程在汛期的安全稳定具有十分重要的价值和作用。文章以某水电站为例,利用模型试验的方法对溢洪道非对称进口导流墙进行优化设计。试验结果显示,优化方案在改善溢洪道水力特征方面的作用显著,不仅可以对溢洪道设计施工提供支持,还可以为溢洪道引渠段的复杂流场分析提供技术保障。

Spillway is the first discharge building in the field of water conservancy engineering, which is of great value and function to maintain the safety and stability of water conservancy project in flood season. Taking a hydropower station as an example, the model test method is used to optimize the design of the asymmetric inlet diversion wall of spillway. The results show that the optimized scheme can improve the hydraulic characteristics of spillway, not only can support the design of spillway, but also provide technical support for the analysis of complex flow field in the approach channel section of spillway.
