幸福堰水闸除险加固布置及水力设计

Reinforcement Scheme and Hydraulic Design of Xingfuyan Sluice

针对幸福堰水闸除险加固工程,重新布置水工建筑物;综合考虑水闸不同的运行方式,分别计算排水过程(闸孔出流或堰流)及相应下游共轭水深,判别下游是否发生淹没水跃,确定是否需要消力池,寻找最不利工况,确定消力池的尺寸;并校核了水闸的综合过流能力,为幸福堰水闸除险加固设计及施工提供依据。

Details of the reinforcement scheme and hydraulic design of the Xingfuyan Sluice are introduced. Hydraulic structures are re - arranged. Discharge processes （ orifice outflow or weir flow） gate water depth are calculated with a comprehensive consideration on different of the submerged hydraulic jump is checked and the necessity of stilling pool and the corresponding downstream conju- operation modes of the sluice. Possibility is then determined. Considering the most unfavorable condition, size of the stilling pool is calculated. Finally, the comprehensive discharge capacity of the sluice is obtained. Calculation results provide useful information to the design and construction of reinforcement.
