| 摘 要： | 由于独柱墩桥梁采用的是单支点支撑，在汽车偏载的影响下，结构的横向抗倾覆稳定受到极为不利的影响。文中总结独柱墩桥梁倾覆事故的经验，以具体的工程为实例，分析了桥坍塌时桥面荷载的大小以及布载的方式。同时，还根据荷载的大小和布载方式，对独柱墩桥梁的抗倾覆能力进行了分析，介绍了相关的验算方法，并提出了加固设计措施。

| Abstract: | The single column pier bridge is used in single fulcrum support, in the influence of automobile eccentric load, the transverse structure of overturning stability is extremely unfavorable influence. This paper summarizes the single column pier bridge collapse accident experience, specific to the project as an example, analyzes the bridge collapse load size and loading way. At the same time, also according to the magnitude of load and load distribution of single column pier bridge, the overturning capacity was analyzed, introduced the calculation methods, and puts forward the measures of strengthening design. |
