跨海施工栈桥稳定性研究

Study on the stability of cross-sea construction trestle bridge

该文结合某特大桥施工栈桥工程实例,建立施工栈桥计算模型,以静力分析为基础,运用有限元分析软件Midas/civil分别对各设计状态的栈桥结构进行屈曲分析,从整体稳定的角度保证了栈桥结构的安全。

Combined with existing sample of Yunte Bridge,this article sets up the calculation model of trestle bridge;based on the static analysis,applying for Finite element analysis software Midas/civil makes eigenvalue buckling analysis of bridge structures on each designed status.By mens of this,from overall stability to ensure the safety of trestle bridge structure.
