摘　　要：通过水工模型试验和船模试验相结合的方法,研究了韩江南溪新建船闸引航道口门区及连接段的通航水流条件及存在的问题。研究表明:受周边环境条件及河势的影响,新建南溪船闸布置空间十分有限,船闸闸室轴线与河道交角较大,导致引航道口门区存在较大横流,通航水流条件较差。由于设计方案上引航道长度短,进闸船舶受横流下推的影响,船舶易碰撞下游导墙引发海损事故。针对船闸平面布置,对设计方案进行了优化试验,提出了满足船舶安全航行条件的船闸布置方案,为工程布置方案的决策提供有力的科学依据,亦可为类似项目提供借鉴。Navigable flow conditions in approach channel,entrance area and connection section of Hanjiang Nanxi new shiplock and existing problems were studied by hydraulic model and ship-model test.Research shows that affected by surrounding environmental conditions and river regime,the layout space of Nanxi new shiplock is very limited,and the intersection angle between lock chamber axis and river channel is large,resulting in large cross flow in the entrance area of approach channel and poor navigable flow conditions.Due to the short length of approach channel of the design scheme,the ship entering the lock is affected by the cross-flow downward push,and the ship is prone to collision with the downstream guide wall,resulting in marine accident.The optimum design scheme was tested for the layout of shiplock,and the layout scheme of shiplock that meet the safe navigation condition was put forward which provided a powerful scientific basis for the decision-making of the project layout and reference for similar projects.
