摘要
洪洞县汾河某大桥为一预应力混凝土空腹式刚架拱桥,该桥结构轻巧、外形美观、受力复杂,采用TDV RMV8i有限元软件对该桥进行建模,根据该桥的施工和使用的实际情况对结构进行屈曲稳定性分析,得出重要结论,可供同类型的桥梁在设计和施工中借鉴参考。
Using the finite element software TDV RMV8i, this paper carried on the modeling of a prestressed concrete open-spandrel rigid-frame arch bridge. According to the actual situation of the bridge construction and use, it also carried out the buckling stability analysis and drew the important conclusions, which provided the reference for the same type of bridges in the design and construction.
