| 摘 要： | 文章基于某跨越既有线大跨径预应力混凝土连续箱梁悬臂施工阶段划分情况,利用Midas/Civil程序软件,建立了三维有限元实体模型,对连续梁桥各施工阶段的主梁内力、应力及挠度进行了仿真模拟分析。结果表明,该有限元分析方法能精确模拟结构的实际受力情况。

| Abstract: | Based on the division situation of cantilever construction period for pre-stress concrete continuous box in a long-span bridge that across the existing line,the article uses Midas/Civil program-ming software to build a 3D finite element model.This model performs simulation analysis on main beam inner stress,pre-stress and deflection during different construction period.The result shows that this model can precisely measure the actual stress condition. |
