| 摘 要： | 为掌握连续刚构桥在悬臂施工阶段应力分布情况，以芦村大桥为例，对连续刚构桥悬臂施工阶段空间应力进行分析研究，建立有限元模型，运用ANSYS分析梁体的力学行为，对各个施工阶段的应力进行计算，通过对比分析，得出比较可靠的结论，可为同类桥梁设计和施工提供参考。

| Abstract: | In order to master the configuratation of stress at the cantilever construction stage and find out some rules, taking the Lucun-River as an example ,a space-stress analysis of the continuous rigid frame bridge at the cantilever construction stage is made.In this paper,the finite element model is established too,and the element analysis program,ANSYS is used to analyze the structure behavior of the continuous rigid frame bridge,and get very important result.The result of which may serve as a reference for th... |
