箱型拱桥全过程受力及稳定性分析

Analysis of the Force and Stability of the Box Arch Bridge in the Whole Process

箱型拱桥因其良好的受力条件以及较为优良的跨越能力,也较多的应用在公路建设中。本文以云南某箱型拱桥为例,采用有限元软件对其建模,从各个阶段的受力对其进行分析,并结合相关规范对其在正常运营状态下的稳定性进行研究。结果表明该桥的受力合理,且稳定性能够满足运营条件,望对类似工程提供参考。

Box arch bridges are often used in highway construction due to their good stress conditions and excellent spanning capabilities.This paper takes a box-shaped arch bridge in Yunnan as an example,uses finite element software to model it,analyzes its forces at various stages,and studies its stability under normal operating conditions in conjunction with relevant specifications.The results show that the bridge's force is reasonable and its stability can meet the operating conditions,and it is hoped that it can provide a reference for similar projects.
