摘　　要：山区连续刚构桥超高墩、高低墩的运用越来越广泛。以云南某连续刚构桥为例,对其主墩设计进行探讨,采用有限元方法对桥墩整体稳定性进行计算,采用理论计算方法对高低墩刚度进行匹配。结果表明,桥墩整体稳定性好、刚度分配合理,可为同类桥墩设计提供参考。The very high-rise pier and high and low pier is used more and more widely among the mountain area continuous rigid frame bridge. In the paper, taking a certain continuous rigid frame bridge in Yunnan Province as background, the design of the main pier of a continuous rigid frame bridge is discussed, the finite element method is used to calculate the overall stability of the pier, and theoretical calculation method is adopted to match the stiffness of high and low piers. The results show that the pier has good overall stability and reasonable stiffness distribution, which can provide reference for similar pier design.
