| 摘 要： | 大跨度混合梁斜拉桥由于结构跨度大和不对称性,稳定性是其必须考虑的主要问题之一.对斜拉桥稳定问题的有限元分析方法进行了阐述,应用有限元软件ANSYS对九江长江大桥的施工阶段和运营阶段的典型工况进行了线性、几何非线性和双重非线性的稳定性分析.计算结果表明,无论是施工阶段还是成桥运营阶段,九江长江大桥的稳定性都满足规范要求.

| Abstract: | Because of its large-span and asymmetry,one of the main problems that long-span hybrid girder bridge should be considered is the stability.Finite element method is adopted to solve the buckling problem of the cable-stayed bridge.Linear elastic,geometrical nonlinear and double nonlinear stability are analyzed on its typical working conditions during the stage of the construction and operation of Jiujiang Yangtze River Bridge by using the finite element software ANSYS.The calculation result indicates that the stability factors of the Jiujiang Yangtze River Bridge meet the standards on the construction stage and operation stage. |
