摘　　要：采用二维水动力数学模型对某中型水库拟建溢洪道内的水流流态进行数值模拟,并利用设计方案中的成果进行模型计算结果复核,验证了该模型对溢洪道进行二维水动力数值模拟的可行性,然后利用该水动力模型对不同泄流工况下的溢洪道内水力要素进行了模拟计算,为溢洪道的设计方案优化提供数据支撑,并对溢洪道的防冲措施及下游跨河大桥的防洪安全提出建议。In this paper,a two-dimensional hydrodynamic mathematical model is used to simulate the flow pattern of a newly-built spillway in a medium-sized reservoir,the feasibility of two-dimensional numerical simulation of the spillway by the model is verified,and then the hydraulic factors in the spillway under different discharge conditions are simulated and calculated by the model,it provides data support for design scheme optimization of spillway,and puts forward suggestions for flood control measures of spillway and downstream river-crossing bridge.
