Abstract: This paper presents a second-order buckling analysis method which must be adopted for arch bridges. The author has developed a second-order buckling analysis computer program, with which the characteristics of parabolic arches, catennary arches and circular arches have been analyzed and the factors effected on arch buckling behaviour have been also discussed.

摘要： 本文讨论了我国桥梁规范关于拱桥稳定分析方法存在的问题。指出对于拱桥的研究也同压杆的研究一样,应由压屈理论过渡到压溃理论。作者编制了二阶稳定分析程序,用该程序计算了几十个算例,根据所得数据和有关资料分析了各类拱的屈曲特性,并对影响拱稳定的因素进行了讨论。
