摘　　要：通过新建红江闸工程水工断面模型试验,研究了闸后水流流态、流速分布等情况,针对设计方案闸下水流衔接不利、海漫跌水严重、流速过大等问题,提出取消消力墩、降低消能防冲段整体高程、调整闸门初始开度等优化措施,明显改善闸后流态,减缓出池水流流速,有效提高了闸下消能防冲能力,保障水闸运行安全。研究成果在工程中得以应用并取得预期成效,可为类似工程的设计和建设提供参考。Through Hongjiang Sluice hydraulic model tests,the flow pattern and velocity distribution of the water flow behind the Hongjiang Gate were studied.In response to the issues of unfavorable energy dissipation under the gate,excessive head fall in the apron,and excessive flow velocity in the design scheme,optimization measures such as removing the energy dissipation pier,decreasing the overall elevation of the section for energy dissipation and erosion prevention,and adjusting the initial opening of the gate were proposed,which improv the energy dissipation and erosion prevention capacity and improve the safety of the gate operation.The research results have been applied in engineering and achieved expected results,providing reference for the design and construction of similar projects.
