摘要
重车过桥时,独柱墩桥容易发生梁体滑移、主梁倾覆等事故.文中以西攀高速金江A匝道二号桥为例,对独柱墩连续箱梁桥的承载能力及抗倾覆验算进行详细分析,根据桥梁表观缺损、材质状况、状态参数等检测结果,采用有限元软件进行结构计算分析,评定桥梁现状,为后期养护决策提供依据.
Abstract
When heavy vehicles cross the bridge,girder sliding and main girder overturning accidents are likely to occur on the single pier bridge.In this paper,the load-carrying capacity and anti-overturning checking calculation of the continuous box girder bridge with single col-umn pier are analyzed in detail,and the status of the bridge is evaluated by finite element software according to the test results of the bridge's apparent defect,material condition and state parameters,providing A basis for the later maintenance decision.
