大跨度钢箱梁桥成桥稳定性分析

Stability Analysis of Long Span Steel Box Girder Bridge

箱形截面梁具有抗弯、抗扭刚度大、整体性好、外形美观等优势,这些优点使得钢箱梁在桥梁建设中占有重要的地位。以在建的钢箱梁桥为研究对象,施工之前模拟分析钢箱梁桥在成桥运营后荷载作用下的稳定性,对施工期间的施工方法、注意事项等有指导意义。

The box section beam has the advantages of bending resistance,torsional rigidity,integrity and beautiful appearance,which make the steel box beam play an important role in the bridge construction. In this paper,the steel box girder bridge under construction is taken as the research object. Before the construction,the simulation analysis of the stability of the steel box girder bridge under the load after the completion of the bridge operation is of guiding significance for the construction method and precautions during the construction period.
