长洲枢纽三线四线船闸平面布置研究

为保证西江黄金水道的畅通,提高长洲枢纽的通过能力,拟在长洲枢纽一线、二线船闸基础上增建三线、四线船闸。受枢纽河段地形条件的影响,三线四线船闸仅有长洲岛右缘和外江右侧台地可供布置。为判别两处位置的优劣,采用定床整体水工物理模型试验和遥控自航船模试验相结合的研究手段,对两处位置船闸布置通航条件进行了研究,分析了工程河段水流特性,研究了船闸上下游引航道口门区和连接段航道通航水流条件和船舶航行条件,确定三线、四线船闸合理可行的工程布置方案。

Research on plane layout of the third-line and the fourth-line ship locks of Changzhou hydro-junction

In order to keep the Xijiang golden waterway clear and improve the waterway capacity of Changzhou Hydro-junction,the third-line and the fourth-line ship locks were planned to build on the basis of the first-line and the second-line ship locks of the Changzhou Hydro-junction.Restricted by the topographic condition,the new ship locks could only be built on the right edge of Changzhou island or the right platform of outer river.To distinguish good and bad site between two sites,the fixed-bed hydraulic model and remote self-propelled ship model were used to research the flow properties and navigation conditions at the upstream and downstream entrance area and linkage section channel of ship locks.Through the research,the feasible site for general layout of the third-line and the fourth-line ship locks was confirmed.
