根据某独柱墩桥梁的倾覆实例,通过仿真计算及倒塌过程推演模拟,揭示了独柱墩桥梁倾覆倒塌破坏过程,了解了桥梁结构在超限荷载下的破坏模式和特点,对评价新建、已建桥梁抗倾覆稳定性并建立相应指标体系,以及如何对抗倾覆稳定性不足的已建桥梁进行加固设计等均有十分重要的现实意义。

According to the collapse case of a single column pier bridge,through the simulation calculation and collapse process deduction simu-lation,this paper revealed the single column pier bridge overturning collapse failure process,understood the failure modes and characteristics of bridge structure under over load,had very important practical significance to the evaluation of new bridge,built bridge anti overturning stability and established corresponding index system,and made reinforcement design to built bridges how to confrontation the insufficient of anti overtur-ning stability.
