内蒙古自治区巴彦淖尔先锋桥整体稳定性分析

Analysis on Overall Stability of Xianfeng Bridge in Bayannur of Inner Mongolia

简要介绍了拱桥空间稳定性理论分析方法,并罗列了国内规范对拱桥整体稳定性验算的要求。最后针对内蒙古自治区巴彦淖尔先锋桥,按规范公式验算和Midas屈曲分析两种方法对其进行了整体稳定性分析,并对两种分析结果进行了对比。

This paper briefly introduces the theoretical analysis method of spatial stability of arch bridge and lists the requirements of checking the overall stability of the arch bridges in China. At last, for Xianfeng Bridge in Bayannur of Inner Mongolia, its overall stability is analyzed according to two methods of standard formula calculation and Midas buckling analysis, and the bridge is summarized and analyzed by comparing two calculation results.
