| 摘 要： | 对独柱墩桥梁横向失稳倾覆机理进行分析，综述目前国内外规范针对桥梁上部结构抗倾覆稳定性计算的有关规定。结合某高架桥工程，选取桥梁位于直线段和曲线段的3跨1联（3×30m），分别对支座反力、支座底部混凝土强度和桥梁抗倾覆稳定系数进行验算，并对计算结果进行对比分析，所得结论对桥梁独柱墩设计具有一定的参考价值。

| Abstract: | This paper analyzes overturning mechanism bridges and summarizes the relevant provisions of current due to lateral instability of singlecolumn pier domestic and foreign specifications for calculation of anti-overturning stability of upper structures of bridges. In combination with some viaduct project, the paper selects 3 spans and 1 connection （3 ×30m） at straight and camber segments of the viaduct and conducts checking calculation for support reaction, bottom concrete strength of support and antioverturning stability coefficient of the viaduct, respectively, and performs comparative analysis for results of calculation. The drawn conclusions provide a certain reference values for design of single-column pier of bridges. |
