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.
