摘　　要：为有效解决因尾水河道防护工程严重水毁对双山灌区渠首枢纽造成的安全隐患,本文建立了平面二维水动力模型,对渠首段水流特征进行了模拟,重点分析了威胁枢纽安全的不利水流条件,提出了二级消力池与跌水相结合的工程治理方案。结果表明,该治理方案能有效改善枢纽尾水河道水流条件,研究成果可为双山灌区渠首枢纽安全治理工作提供技术支撑。In order to effectively solve the safety risks caused by severe flood damage to the canal head junction of Shuangshan Irrigation District due to the tail-water river protection project, this paper establishes a planar two-dimensional hydrodynamic model,simulates the flow characteristics of the canal head section, focuses on the analysis of adverse flow conditions threatening the safety of the hub, and puts forward a project treatment scheme combining the secondary hydrostatic pool and the fall water. The results show that the treatment scheme can effectively improve the flow condition of the tailwater channel of the junction, and the research results can provide technical support for the safety treatment of the canal head junction in Shuangshan Irrigation District.
