摘要
依托湘江株洲航电枢纽扩建二线船闸工程,采用定床物理模型,从船闸通航条件角度对扩建二线船闸与一线船闸相邻布置时两线船闸轴线间距选择进行研究。重点分析了扩建二线船闸不同轴线位置对两线船闸上、下游口门区和连接段航道的通航水流条件影响规律,提出了新老两船闸轴线间距在满足两线航道宽度要求和施工安全的前提下应尽量减小的轴线选取原则。
Based on the second-line ship lock extension project of Zhuzhou Navigation Power Junction in Xiangjiang River, the fixed bed physical model was established. According to the ship lock navigation condition, the spacing distance selection of axis between the second-line ship lock extension project and the first-line ship lock was studied. The effect laws of different positions of axis in the second-line ship lock extension project on the navigation flow condition of approach entrance area and connecting section were analyzed emphatically. On the premise of meeting the requirements of channel width and ensuring construction safety, the selection principle of axis was proposed, the key of which was to decrease the distance between the old and new ship lock axes as much as possible.
