摘　　要：本文在景宁县金村水库“L”形侧槽溢洪道设计方案模型试验初步研究的基础上,针对原设计方案存在的问题进行改进优化,通过FLOW-3D进行数值模拟方案比选,并确定推荐方案。后期再依据此推荐方案进行模型试验,对其水力特性进行深入研究分析,并最终确定其结构布置、掺气减蚀设施和消能形式,为工程实施提供理论依据。The preliminary research is carried out on the“L”-shaped side-slotted spillway design scheme of Jincun Reservoir in Jingning County was carried out,the existing problems of the original design scheme were improved and optimized through the model test in the early stage of this paper.The problems in the former design plan are improved and optimized.The numerical simulation scheme is compared and selected through FLOW-3D,and the recommended scheme is determined.Model test is implemented according to the recommended plan accordingly in the later stage.In-depth study and analysis are carried out on its hydraulic characteristics.The structure layout,cavitation erosion reduction facilities and energy dissipation type are finally determined,thereby providing theoretical basis for project implementation.
