摘　　要：针对泗阳一线船闸大修改造后的下游闸门使用状况,介绍船舶撞击力的计算方法,并利用有限元法对闸门正常使用工况和受船舶意外撞击工况进行分析计算,对各种工况下闸门关键部件和关键部位的应力变化情况进行研究,从而搞清了船舶撞击力对船闸安全运行的影响。Combining with the work condition of lower gates of Siyang lock No.1 repaired and reinforced previously, this paper introduces the calculation methods of ship impact force. Based on the analysis of the normal work and collision conditions of lock gates by the FEM, and the study on the stress distribution and variation of the key members and parts of lock gates, the influence of ship＇ s collision on safety of lock gates is known clearly.

关 键 词：船闸闸门 撞击 应力变化 安全影响
