摘要
以斯木塔斯水电站为例,针对原矩形窄缝挑坎不能满足工程需求的问题,提出了一种Y型窄缝挑坎的体型设计方案,通过模型试验分析了不同工况下该体型流速、压强、水舌形态等各项水力特性。结果表明,Y型窄缝挑坎各项水力特性良好,消能效果显著。
Taking the Simutasi hydropower station for an example, the project form design scheme of Y-shaped slit-bucket is proposed to solve the problem of previous rectangular slit-bucket which can not meet the project demand.Model test is used to analyze hydraulic characteristics at different operating conditions,such as velocity,pressure,nappe shape.The results show that the hydraulic characteristics of Y-shaped slit-bucket are better and the effect of energy dissipation is remarkable.
