摘要: 以云南省海口大桥为研究对象,基于ANSYS软件分别考虑墩底固结和土.桩.结构相互作用,建立了该桥的两 种三维有限元模型,以此为基础进行了两种模型的自振特性对比分析;并系统地介绍了两种中承式钢管砼系杆拱桥 简化模型的构建方法,可为相关研究提供参考.

关键词: 自振特性, 中承式钢管砼拱桥, 有限元法, 土-桩-结构相互作用

Abstract: Haikou Bridge is a concrete-filled steel tubular arch bridge with a main span of 150m.Taking that bridge as an example, based on the software ANSYS,two kinds of spatial finite element models for the bridge were respectively established, under the consideration of the pier bases concretion and the interaction between the soil and the pile.Calculation analyses results of natural vibration of the two models are comparatively analyzed.The establishment method of the two models of the half-through concrete—filled steel tubular arch bridge is provided,which can be reference for relative research.

Key words: natural vibration, half-through concrete-filled steel tubular arch bridge, finite element method , soil-pile-structure interaction
