摘    要:以麻桥水闸为例,对闸上游10年一遇洪峰过程遭遇闸下游不同时刻5年一遇水位过程进行调洪演算,分为7种工况计算围内的最高涝水位和水闸最大过流能力,计算结果显示,采用上游洪峰遭遇下游最高水位前1h进行调洪演算得到的内涝水位最高,过流流量最大,为水闸安全鉴定和除险加固提供相应的依据。

关 键 词:水闸工程;调洪演算;最高涝水位;排涝分析

Abstract:Takes Maqiao sluice as an example , and flood regulating calculation has been carried out , which the flood occurred on the flood peak process of the upstream with ten -year return period which encounters water level process of the downstream in the different time with five-year return period .This calculation covers the highest flood water level in the sluice and the maximum flow capacity in seven working conditions .The result shows that the flood regulating which is done in the first hour when the flood peak of the upstream encounters the highest water level will make the waterlogging level the highest and the rate of flow maximum .This will provide basis for the safety appraisal and reinforcement of sluices .
