摘要
通过对已设计的四座钢管混凝土拱桥的拱轴线采用不同线型时的内力分析,得出了一些规律,其可供设计钢管混凝土拱桥选择拱轴线型时参考。
In this paper some rules have been attained according to internal forces analyses of in the four designed CFST arch bridges while adopting different arch axial linetypes.These conclusions may be referrences for selecting arch axial linetype in bridge designed.
