对新疆肯斯瓦特溢洪道及消力池建立了三维模型，采用结构网格和非结构网格结合的方式对模型进行了网格划分，利用Realizable k －ε紊流模型和VOF模型相结合的数值方法对其三维流场进行了数值模拟，结果表明，原设计方案下水流不稳定，消力池内消能效果较差。为此提出在消力池内增加T形墩的修改方案，增设T形墩后消力池内水流对称，消能效果显著提高，可达到工程设计要求。由此可见，数值模拟方法能够作为试验的补充方法，为工程实际应用提供依据。

In this paper,the three-dimensional model of Kenswatt spillway and stilling basin in Xinjiang was established. The model was meshed by using the structural and non-structural grids,calculated with the Realizable k-εturbulence model and VOF method and the water flow field was simulated. By the calculation,it shows that the flow is unstable and the energy dissipation effect in stilling is poor under the original design. Therefore the modification of adding T-shape pier in the pool is proposed. After adding T-shape pier,the flow pattern is symmetrical,energy dissipation effect is improved obviously,the design can reach to the requirements of engineering. So we can see that the numerical simulation meth-od can be used as complementary experimental methods and provided the basis for practical application.
