The three-dimensional flow field of spillway was numerically simulated using FLOW-3D software.The optimal solution include adjusting plane arrangement of spillway,pulsing bucket and changing pre-dug hole extent of the original spillway.Combining hydraulic model tests,flow pattern,velocity distribution,water surface profile and other hydraulic characteristics of the original program and optimal program flow were analyzed.The value of hydraulic model tests and numerical simulation calculations are in good agreement,which demonstrate the effectiveness of optimization,also shows the feasibility of three-dimensional numerical simulation.
