摘要
坝身泄水孔是拱坝的常见泄流方式,但是这种设计也存在大流量泄洪时的水舌向心集中问题。文中以大石牛电站为例,对坝身泄水孔体型设计展开研究,并提出了优化设计方案。模型试验和数值模拟结果显示,该方案可以解决原设计方案的问题,并且总体安全,可以在相关水工设计中借鉴应用。
The discharge hole through the dam is the common flow discharge type for the arch dam. But the design has a problem of centripetal concentration of jet flow when the large flow flood discharge. Taking the Dashiniu hydropower station as an example, the paper studies the design of the body shape of discharge hole through dam and provides optimal design scheme. The results of model test and numerical simulation show that the scheme could solve the problem of the original design and is overall safety. It could be applied for reference in related hydraulic structure design.
