采用RNGκ-ε紊流模型和VOF方法对某工程带差动型挑坎的溢洪道流场进行了三维数值模拟研究，详细描述了差动坎处的流速、压强等水力参数的分布规律，得出了高低坎挑射水舌的挑距、入水角。将部分结果与试验对比，符合良好，验证了数值模拟是准确可靠的，可作为模型试验的有益补充，为挑坎设计提供重要的参考依据。

Water flow 3D numerical simulation was conducted for a spillway with differential bucket by use of RNGκ-εturbulent model and VOF method. Distribution of flow velocity and pressure as well as other hydraulic pa?rameters at the differential bucket were described in detail. The outcomes also include the horizontal distance be?tween high and low water tongue as well as the inflow angles. The results of simulation conforms well to that out of model tests,demonstrating that numerical simulation is reliable method and is useful supplement of model test. It can provide important reference for the design of bucket.
