摘　　要：阐述ABAQUS三维有限元软件基本原理,以中型水闸江苏大丰四卯酉闸为例,利用ABAQUS对其反拱底板建模并分析应力情况,并对有限元法、控制点协调法和连拱弯矩分配法计算结果进行了比较,得出有限元法分析结果更为准确的结论。This paper describes the basic principle of Abaqus 3D finite element software,and takes the medium-sized sluice of Jiangsu Dafeng Simao-you sluice as an example,and uses Abaqus to reverse it,the stress of the arch floor is modeled and analyzed.The results of the control point coordination method and the moment distribution method of the arch are compared,and the results of the finite element method are more accurate.

关 键 词：有限元 反拱底板 控制变为协调法 连拱力矩分配法
