摘　　要：水利工程领域中对于溢流坝鼻坎的角度选取是一直备受关注的问题,然而对于物理模型试验不仅费时费力,而且周期长影响工程的进度。以较成熟的flow-3d软件对不同角的鼻坎溢流坝进行三维数值模拟,通过模拟的水力特性参数结果分析,得出随着鼻坎角度的不同各水力参数都发生改变,就实际工程具体的研究分析得出合理的鼻坎角度。In field of water conservancy projects, the selection of spillway bucket angles is always a concerned problem. However, physical model experiment is time - consumirlg, laborious and long - period, which will impact on the project schedule. Based on ma- ture flow - 3d software. This paper carried out three - dimensional numerical simulation to analyze different spillway bucket Angles. Though the results of hydraulic characteristic parameters, it showed that the hydraulic parameters of different Angle had changed, the reasonable angle of bucket should be obtained from the research and analysis of actual engineering.
