摘　　要：钢管混凝土劲性骨架拱桥优点是其跨越能力强,施工简便等,在日常设计中得到了广泛应用。钢管混凝土劲性骨架拱桥在修建过程中,施工加载顺序,对于结构的安全至关重要,在设计时应进行详细计算分析。文章结合某中承式劲性骨架箱肋拱桥,对其在施工、运营过程中的静、动力特性分析进行了阐述,供同行参考。The advantage of arch bridges with stiff steel-pipe concrete framework is the good ability of span and easy construction so that the technology is widely applied. In the construction of this kind of bridges, the sequence of construction is of great importance to safety of the structure, so the design should conduct detailed analysis. The paper presents the analysis of the static and dynamic characteristics in the construction and operation according to the construction of this kind of bridges.

关 键 词：拱桥 结构静力 稳定性
