以贵州省三都到独山高速公路的打见河大桥为工程背景，采用三维有限元分析软件Midas对山区高墩连续刚构桥进行空间稳定性分析，对比分析不同结构形式桥墩成桥阶段的稳定性，对于山区高墩连续刚构桥，双肢箱形薄壁墩更能满足桥梁稳定和变形的要求。%Taking the Dajian river bridge in Guizhou Sandu to Dushan highway as the engineering background, this paper made spatial stability a-nalysis on mountain high pier continuous rigid frame bridge using 3D finite element analysis software Midas, comparatively analyzed the stability of different structures type piers bridging stage, for mountain high pier continuous rigid frame bridge, double legs thin-walled box pier could meet the requirements of bridge stability and deformation.
