| 摘 要： | 以某大跨度中承式钢管混凝土拱桥为例，基于ANSYS软件建立了该桥的三维有限元模型，研究了考虑桩一土一结构相互作用对大跨度钢管混凝土拱桥静风风致反应的影响。结果表明，当基础刚度得到保证后，采用拱脚固结模式进行抗风分析是可行的。

| Abstract: | Taking a long-span concrete-filled steel tube arch bridge as an example,based on the software ANSYS,the spatial finite element models for the bridge are build. The effects of pile-soil-structure interaction on the long-span concrete-filled steel tube arch bridge to wind-induced response are studied. The results show that the arch foot fixed model can be used for wind resistant analysis on the condition the rigidity of the pile foundation is ensured. |
