摘　　要：本文采用通用有限元分析软件ANSYS对大跨度圆弧形拱式跨越管道进行参数化建模,并计算了所建模型在多种静力荷载共同作用下的变形与应力分布情况,可为圆弧形拱式跨越管道的设计提供参考;此外,还对本结构不同壁厚、不同管径的模型进行了稳定性分析,以探究管道稳定性的影响因素。The deformation and stress distribution of long span circular arch suspending pipeline in various of static loads were calculated and analyzed in this paper with finite element analysis software ANSYS, which might provide a reference for design. Otherwise parametric stability analysis was carried on by changing the wall thickness and pipe diameter of the pipeline models to explore the factors that influence the stability of the pipeline.
