| 摘 要： | 针对高低挑坎对冲消能工上下水舌正碰后合股水流平抛的水力过渡过程,推导出该过程发生的控制方程组.上下水舌正碰可以达到最佳的消能效果,合股水流平抛加大挑距,减小水流在下游的入射角进而减轻对河床的冲刷.

| Abstract: | The control equations concerning the hydraulic transient course of energy dissipation by upper & lower flip bucket on high arch dam are set up.In this course,the upper discharged nappe collides with the lower discharged nappe front to front to attain best effect of energy dissipation in vertical direction while the total discharge at the confluent point is thrown away with horizontal velocity and falls to the downstream bay with less incident angle to lighten scouring the river bed. |
