| 摘 要： | 兰督水利枢纽溢洪道泄洪的水流与河道正交、顶冲回流、消能防冲等问题较为突出，本文在理论计算的基础上，通过水工模型试验优化、检验、设计出较完整的扩散扭曲挑流鼻坎体型，与原设计的单侧平面扩散舌形挑流鼻坎体型相比，坎后水流流态及消能效果有了很大的改善。

| Abstract: | Because flow relieving from the spillway of Lan Du Water Project is placed at right bank of the river,the problems of flow scouring up,return flow and energy disipators are very serious. In order to solve these problems,the jet bucket which is designed as a divergence and torsion face is expounded after doing hydraulic model test based on theoretical calculation.The results show that the character of flow behind the bucket and the effect of energy disipators are advantage to the old one which is designed as divergence plane. |
