摘　　要：通过数值模拟计算与整体水工模型试验,验证溢洪道泄流能力能否达到设计标准,并且运用流体力学软件FLOW-3D建立三维数学模型,在数模计算的成果上进行物理模型试验验证,对不同洪水工况下泄水建筑物水流流态、流速、水面线、压力、消能效果进行试验分析,得出数模结果与物模试验结果相近、变化规律基本相同的结果,通过2种方法验证了泄水建筑物体型布置及设计的合理性,根据试验结果提出合理化优化方案,为泄水建筑物设计及运行管理提供科学依据。Through numerical simulation calculation and the overall hydraulic model test two ways,verify that the spillway ability can meet the design standard.Using the fluid mechanics software flow-3d to establish a three-dimensional mathematical model,the physical model test is tested in the results of numerical calculation.The flow state,velocity,surface line,pressure and energy efficiency of drainage buildings in different flood conditions were analyzed.The numerical results are similar to the test results,and the changes are basically the same.The rationality of the layout and design of drainage buildings is verified by two methods.According to the experimental results,the optimization scheme is proposed,and provide scientific basis for the design and operation management of drainage buildings.
