摘　　要：简述了钢管混凝土拱桥的优缺点,并对其缺点提出解决方案——钢管混凝土复合拱桥,对该种桥型的设计施工作出简要概述,指出该桥可以提高拱肋的横向稳定性,减小横向地震力作用。Sketch the advantages.and disadvantages of concrete filled steel tubular arch bridge, and to its shortcoming proposed that the solution-concrete filled steel tubular compound arch bridge, and makes brief outline to this kind of bridge＇ s design and construction. Points out that the bridge can improve the transversal stability of the arch rib and reduce the transversal seismic force.

关 键 词：钢管混凝土拱桥 横向稳定 横向抗震性能 钢管混凝土复合拱桥
