摘要
灵璧船闸是新汴河复航工程中的重要节点,其规模较大、水力指标较高。根据新汴河复航工程的特点及船闸总体布置,按照《船闸输水系统设计规范》要求,研究确定了灵璧船闸采用短廊道集中输水系统形式,计算了输水阀门处廊道断面的面积,提出了具体的输水系统布置,确定输水阀门开启方式,并采用船闸输水过程数学模型计算闸室输水水力特性。研究成果表明:提出的输水系统布置和确定的输水阀门开启方式合理可行,各输水水力特性值满足设计和规范要求,能够达到预期的设计目标。
Lingbi ship lock is the key node of the resailing project of New Bianhe River,which has quite large scale and high hydraulic indexes.According to the layout characteristics of the resailing project of New Bianhe River and the ship lock and the demands of the Design Code for Filling and Emptying System of Ship Locks,the type of filling and emptying system of Lingbi ship lock is put forward to be short-culvert concentrated filling and emptying system.The area of the culvert transect at the valve is calculated,and the detailed layout of the filling and empting system and the valve opening modes are designed.Moreover,hydraulic characteristics during lock filling and emptying are calculated by lock filling and emptying mathematical model.The results indicate that the detailed layout of the filling and empting system and the valve opening modes is reasonable,and the hydraulic characteristics can fulfil the design and criteria demands and be able to achieve the desired design objectives.
