应用RNG k-着湍流模型和有限差分法对兴隆水利枢纽工程鱼道的设计模型和另外2种对比模拟模型进行了数值模拟计算，分析了过鱼池的流态、紊动能和紊动能耗散率等指标，并对比分析了不同孔口布置的淹没孔口式横隔板鱼道的水力特性。结果表明：兴隆水利枢纽鱼道具有良好的消能效果，相邻隔板孔口异侧布置比同侧布置消能效果好；可以通过改变淹没孔口式鱼道隔板的孔口位置、数目及尺寸进行体型优化。

The design model and other two reference models of the fishway in Xinglong Hydro-Junction Project were numerically simulated by the RNG k-εturbulence model and the finite difference method. The flow pattern and parameters, such as turbulent kinetic energy and energy dissipation rate, were analyzed. The hydraulic characteristics of the submerged orifice transverse diaphragm plate fishway with different orifice layouts were compared and analyzed. The results show that energy dissipation effect of the fishway in Xinglong Hydro-Junction Project is good. The energy dissipation effect with the opposite arrangement of adjacent baffles' orifice is better than that with the ipsilateral arrangement. The submerged orifice transverse diaphragm plate fishway can be optimized by changing the position, amount and size of the orifices. It has a strong plasticity and good application prospect.
