摘　　要：钢管混凝土拱桥力学模型有多种简化模拟方式,但每种模拟方式是否都能比较接近地反应出拱桥的真实动力特性及其对动力特性影响有多大,还尚未研究。本文将建立三种不同的有限元力学模型,分析其不同的模拟方式对拱桥动力特性的模拟是否相近。The model of concrete-filled steel tube arch bridge have some simplify simulation ways, but it has not studied yet that whether each simulation way can reflect the true dynamic characteristic of the arch bridge and how serious to influence the dynamic characteristic. This article will set up three kinds of different finite element models and analyze whether the different finite element models can simulation the dynamic characteristic of the concrete-filled steel tube arch bridge similarly.
