摘    要:钢管混凝土拱桥在成桥状态下刚度比较大,但是在施工阶段,尤其是采用缆索分段吊装施工时,刚度较小,而且随施工阶段不断变化。采用有限元方法,建立了三维模型,对处于台风区的东莞水道特大桥在主拱吊装阶段的动力特性进行了计算分析,为该桥的顺利建成提供了科学数据。

关 键 词:钢管混凝土拱桥  有限元  分段吊装  动力特性

Abstract:Steel tubular arch bridge has a large stiffness in the finished dead state, but in the construction stage, especially at the stage of cable segmental hoisting, its stiffness is very small, and changes with construction. Adopting the finite element method, this paper sets up a three - dimensional model, to calculate and analyze the drive characters of Dongguan Shuidao extra-large bridge at the stage of main arch hoisting in the typhoon area, which provides scientific data for the bridge' s successful building. The model analysis and result can be of reference value for similar bridges.
Keywords:steel tubular arch bridge  finite element  segmental hoisting  drive characters
