利用标准k-ε双方程湍流模型，采用VOF法追踪自由水面，应用瞬态PISO算法求解压力-速度耦合的方法，采用结构化网格并在溢流坝顶进行网格加密，模拟计算了七孔溢洪道流场的三维水力特性，得到了设计工况的泄流能力、水面曲线、速度场。通过物理模型试验验证，两者结果吻合较好。

The standard k -ε two equation turbulance model and VOF method are adopted to track free surface. Transient PISO algorithm is applied to the solution of pressure- velocity coupling. Three-dim- entional hydraulic characteristics of seven-hole spillway flow field is simulated and calculated by adopting structure grid and the mesh refinement to the top of spillway. On the basis of these, the discharge capacity of design condition, surface profile and velocity field are available. At the same time the physical model test is also verified, the results of both tests tally well.
