摘　　要：通过概化模型计算并结合工程实例分析,研究了凹形和凸形河岸对低水头枢纽船闸口门区水流条件的影响,指出了对低水头枢纽船闸口门区通航水流条件相对有利的河岸形态。不仅可作为枢纽总体布置阶段船闸优化布置参考的一个方向,而且在枢纽坝址选择阶段就可以加以考虑,以减小枢纽总体布置的难度及工程量,为船闸通航创造良好的水流条件。This paper studies the influence of different riverside shape on the flow condition of low-head hydraulic lock＇s outlet area through mathematical computation and examples of project, and finds out the riverside shape which is the most advantageous one. The achievement may not only serve as a reference for optimum arrangement of ship lock during the overall layout stage, but also can be considered during dam site choice stage, so as to diminish the difficulty of project layout, and create favorable flow condition for navigation.
