大江水库溢洪道消能工优化研究

The optimization of energy dissipators of Dajiang reservoir spillway

用水工整体模型试验方法重点研究了广西荔浦县大江水库溢洪道消力池的池长 ,尾槛高度 ,池内消能工的作用 ,以及下游垭口不同开挖程度对泄洪和消能的影响 ,优化了消能工的型式、尺寸及布置 .

Through the whole hydraulic model test,we study mainly on the length of the stilling basin of Dajiang reservoir spilway,the altitude of tail threshold,the function of energy dissipators,and the influence on flood discharge and energy dissipation by the cut of the lower reaches valley.Then,the types and the dimension of the energy dissipators and their collocation are optimized.
