摘　　要：在偏心偶然超载作用下,独柱墩桥梁可能发生整体横向失稳。通过对独柱墩连续箱梁桥的抗倾覆能力分析,并以云南省武定至昆明高速公路共9座独柱墩箱梁桥的抗倾覆验算为工程背景,运用有限元分析程序MIDAS/CIVIL2006,对其中横向受力最不利的箱梁进行了整体抗倾覆验算,并有针对性的提出应对措施,以避免发生支座脱空现象导致侧倾,提高桥梁的抗倾覆能力。Under the action of the eccentric accidental overloading, the overall lateral instability of single column pier bridge may occur. Through to the analysis of the ability against overturning on continuous box girder bridge, and WuDing to Kunming highway in Yunnan Province a total of 9 single column pier box girder bridges resistive overturning checking calculation for the engineering background, by using the finite element analysis program MIDAS/CIVIL2006, to check the overall stability against overturning of the box girder under the worst lateral force, and put forward some corresponding countermeasures, to avoid the phenomenon of bearing separation and enhance the ability of bridge stability against overturning.
