摘　　要：本文基于某钢筋混凝土双曲拱桥加固改造实例,分析其加固前后活载横向分布系数,并将空间有限元分析的基础上得到的横向分布系数与弹性支承连续梁法的计算结果进行比较与分析,总结拱桥平面分析模型建立的方法。Based od the example of a RC double arch bridge＇ s reinforcing in this paper. The lateral distribution of load was analysed before and after the bridge＇ s reinforce, it has taken the comparison of analyzing three finite element models by ANSYS software and continuous beam with elastic supporters, a method that is helpful to build the plane FE model of double arch bridge is presented.
