结合某低水头航电枢纽泄水闸断面水工模型，对消力池布置方式和差动式尾槛对消能及过沙效果的影响进行模型试验研究。结果表明，将消能墩摆放在泄水闸局部开启时底流最大流速区附近且适当调整消力池长度，以及合理设计差动式尾槛的出池坡度和尾槛长度，可以在保证消力池消能效果的同时，增强消力池内过沙效果。
結閤某低水頭航電樞紐洩水閘斷麵水工模型，對消力池佈置方式和差動式尾檻對消能及過沙效果的影響進行模型試驗研究。結果錶明，將消能墩襬放在洩水閘跼部開啟時底流最大流速區附近且適噹調整消力池長度，以及閤理設計差動式尾檻的齣池坡度和尾檻長度，可以在保證消力池消能效果的同時，增彊消力池內過沙效果。

On the basis of cross?sectional hydraulic model test of a low?head navigation hydro?junction, the in?fluences of stilling basin arrangement and differential tail sill on energy dissipation and over sand effect were stud?ied. The results show that in order to guarantee the effect of energy dissipation and enhance the effect of over sand, the energy dissipation piers are located near the maximum velocity zone of end flow, and the length of the stilling ba?sin is adjusted. The slope out of the pool and the last sill length of differential tail sill are designed rationally.
