摘要
针对通过能力日益增长背景下的多线船闸输水系统设计问题,以西江长洲枢纽四线船闸群为例,总结了不同阶段通过能力需求引起的船闸设计规模变化。针对二线船闸规模小、一线船闸闸室宽度大、三线四线船闸并列布置同步建设且规模巨大的特点,分别介绍了各船闸输水系统的设计理念。采用物理模型试验手段,提出了二线船闸采用消力槛强迫消能、一线船闸采用双明沟消能、三线四线船闸采用互通省水布置等创新成果,并通过原型观测验证了创新成果实效性。提出两条建议:多线船闸总体布局应将高等级船闸布置在河心侧、低等级船闸布置在河岸侧,输水系统设计应综合考虑地质条件、结构形式、水力指标等因素。
In this paper,focusing the filling and emptying system design for multi-lane locks under increasing demand of traffic capacity,and taking the four-lane locks of Changzhou Junction on Xijiang River as an example,the dimension variation of these locks under the demand development of traffic capacity has been summarized,the design considerations of the filling and emptying system for each lock has been introduced according to its characteristics,that the 2nd lane lock has small dimension,the 1st lane lock has wider chamber,and the 3rd and 4th lane locks are paralleling twin locks with huge dimension,the innovative results such as baffle sill energy dissipation device used in the 2nd lane lock,double open ditches energy dissipation device used in the 1st lane lock and interconnected water saving layout used in 3rd and 4th locks have been put forward.Some advices have been given for references such as overall layout for future multi-lane lock should put the large lock at the riverside and put the small lock at the bank side,and the filling and emptying system design should consider the geological condition,structure pattern and hydraulic indexes,etc.
