摘　　要：本文利用大型通用有限元分析软件ANSYS采用参数化建模对自承式管架桥在静力荷载下的变形和内力进行分析,并进一步分析了支座宽度和包裹角度的变化对结构的影响,提出力学性能更为合理的结构设计建议。The stress peorormance of self-supporting pipe bridge under static load with ANSYS software based on parametric modeling were analyzed in this paper, then models comparison by changing the bearing width and its package angle were researched to identify the better mechanical performance. In addition, suggestions for design were given out to achieve optimization.
