摘要：A 3D flow field numerical simulation for a stepped spillway was established under the design flood level and the check flood level respectively ,in order to fully research the impact of the steps on the overflow .In which the standard k ~ ε model was used to simulate turbulence and the VOF method to track the free surface .The results of the free water surface ,bottom pressure and velocity were compared and analyzed with the model test data .They were in good agree-ment .The numerical simulation can provide smoother and completer flow field information rapidly .It can be seen that the maximum negative pressure is on the vertical surface of the first step ,which can provide reliable theoretical basis for the spillway optimal design .
