采用正态物理模型研究湘江株洲航电枢纽扩建二线船闸工程对一线船闸通航条件的影响。分析工程前一线船闸通航水流条件，二线船闸建设对原有边界条件的改变，工程后一线船闸上下游引航道口门区及连接段航道的横、纵向流速等水力参数变化规律，以及口门区现有导流建筑物对新建工程的适应性等。结果表明，二线船闸建设使得一线船闸通航水流条件稍有恶化，但水流条件的改变对船舶航行条件影响不大，工程前后船舶进出一线船闸的航行条件基本一致。% Based on normal physical model test, we analyze the influence of the first-line ship lock navigation condition on the second-line ship lock construction of Zhuzhou navigation power junction in Xiangjiang river, the navigation conditions of first-line ship lock, changes in the original boundary conditions after the second-line ship lock construction, variation of hydraulic parameters on the first-line ship lock approach entrance area and the lower connection on the channel, as well as the adaptability between the existing training structure and the new construction. The results show that the influence of the second-line ship lock construction on the first-line ship lock navigation condition is limited, and the navigation condition of the first-line ship lock is the same as that before the new construction.
