【摘要】 对竖缝式圆形鱼道的水力特性展开深入研究。综合分析了水位变化、水流流态以及紊动能分布等方面的规律。研究结果表明，鱼道内沿程水位沿水流方向平缓下降，主流区较为明显，有助于鱼类洄游时感应方向，流速与水位、紊动能与水位均呈正相关关系。本研究成果可为竖缝式圆形鱼道的科学设计与高效运行提供理论支撑，有助于进一步提升水利工程建设中的生态友好性，促进鱼类资源的保护与可持续发展。更多还原

【Abstract】 This paper conducts an in-depth research on the hydraulic characteristics of vertical slot circular fishways. A comprehensive analysis was made on the laws of water level changes, flow patterns, and turbulent kinetic energy distribution etc. The results of research indicate that the water level in the fishway drops gradually along the flow direction; the main flow region is rather distinct, which is beneficial for fish to perceive the direction during migration; both the flow velocity and the turbulent kinetic energy have a positive correlation with the water level. The research results can provide theoretical support for the scientific design and efficient operation of vertical slot circular fishways, contribute to further improving the ecological friendliness in the construction of water conservancy projects, and promote the protection and sustainable development of fish resources.更多还原
