中高水头船闸输水系统选型布置及试验研究

Type selection and test research of filling and emptying system in medium and high head ship lock

以贵州旁海枢纽工程船闸为例,根据国内已建船闸综合分析所得的输水系统选型指标,利用灰色系统理论对船闸输水系统选型和布置进行验证,并应用物理模型试验对船闸水力特性和阀门工作条件进行试验研究。通过试验测定闸室内停泊条件和阀门开启方式,确定并优化了船闸结构和输水系统布置。结合近年来船闸输水系统设计、工程实际经验和成果,为第二类分散输水系统和平板阀门在中高水头船闸工程的设计和应用提供参考。

Taking the ship lock of the Panghai junction in Guizhou province as an example,this paper uses the gray system theory to verify the filling and emptying system selection and layout based on the comprehensive analysis of the built ship locks in China.The physical model test conducts an experimental study on the hydraulic characteristics of the ship lock and the valve operating conditions.The berthing conditions and valve opening methods in the lock room were tested and determined,and the lock structure and filling and emptying system layout were determined and optimized.Combining ship lock filling and emptying system design and engineering practical experience and results of recent years,we provide a reference for the design and application of the second type of decentralized filling and emptying system and flat valve in the middle and high head ship lock project.
