摘　　要：文章以公路桥梁通用图(20+32+20)m连续箱梁为工程背景,通过Midas软件计算出独柱墩连续箱梁桥支反力与抗倾覆稳定系数,并根据支座反力及抗倾覆稳定系数分析曲率半径对弯梁桥稳定性的影响,得到了桥梁抗倾覆稳定性随曲率半径的变化规律,为此类独柱墩桥梁设计提供技术参考。With Highway Bridge General Atlas（20＋32＋20）m continuous box girder as engineering background,this article calculated by Midas software the reaction forces and anti-overturning stability factor of single-pile pier continuous box girder bridge,analyzed the impact of curvature radius on the stability of curved girder bridge according to support reaction forces and anti-overturning stability factors,then obtained the variation rules of bridge anti-overturning stability with the curvature,radius,thereby providing the technical reference for the design of such single-pile pier bridges.
