摘　　要：为研究船闸不同规模和尺度下口门区及连接段的通航水流条件,以长江上游某规划枢纽为依托,采用整体水工模型试验和船模试验相结合的方式,从流速、流态等方面对双线小船闸、双线大船闸和三线大船闸3种方案船闸引航道口门区及连接段的通航条件进行了研究。结果表明:枢纽运行方式、船闸规模等因素对通航水流条件影响显著:双线小船闸方案口门区及连接段通航水流条件较好,但船闸有效尺寸小,通过能力有限;三线大船闸方案通过能力可满足未来50年货运量的增长需求,虽口门区最靠近主流通航条件略差,但通过泄洪闸和电站机组的优化调度,口门区及连接段的水流条件基本能满足通航要求;双线大船闸方案的通过能力和水流条件均介于其他两方案之间。For the study of the navigation condition of shiplocks in different sizes and scales in combination with the overall hydraulic model test and ship model test,the flow condition at the entrance and connection areas of double-lane small lock,double-lane big lock and three-lane big lock schemes has been analyzed in terms of flow velocity and pattern.The results show that the hub operation,lock scales and lanes play a significant role:the double-lane small lock has a better navigation flow condition,but with a limited capacity;the three-lane big lock has a slightly worse navigation flow condition but,through optimal scheduling of the flood discharge gate and the power station,can basically meet the navigation requirement while the capacity and flow condition of the double-lane big lock are just in between.
