摘　　要：为了解预应力混凝土单箱梁矮塔斜拉宽桥的受力特性,以一座四跨预应力混凝土矮塔斜拉宽桥为工程背景,采用有限元模型对该桥进行平面模型及空间模型的数值分析。通过对两种模型计算结果进行数值比较,得到该类型桥梁的纵、横向受力特性,进一步对该类桥梁的设计提出有参考价值的建议。On the background of one pre-stressed concrete partially cable-stayed wide bridge of simple box, the writer made some numerical analyses by building 2D and 3D finite element models to find out its mechanical characteristics. By comparing the results of two kinds of models, the writer acquired longitudinal and transverse stress characteristics of this kind of bridges and gave some valuable advises for designing of the same kinds.
