摘　　要：以公路桥梁通用图为工程背景,通过midas计算出了独柱墩连续箱梁桥支座反力,并计算了抗倾覆稳定系数,根据支座反力及抗倾覆稳定系数,分析了支座布置形式对连续箱梁桥稳定性的影响,得到了桥梁抗倾覆稳定性随支座布置形式的变化规律。Regarding Highway Bridge General Atlas as engineering background,calculated the bearing reaction of single column pier continuous box-girder bridge through program midas and further calculate anti-overturning stability coefficient,analyzed the influence of setting different seat form to the stability of continuous box-girder bridge according to the bearing reaction and the anti-overturning stability coefficient,got the change regulation of the bridge's stability against overturning following set different seat form.

关 键 词：连续箱梁桥 独柱墩 抗倾覆稳定 MIDAS
