| 摘 要： | 脱空对钢管混凝土拱桥受力特性的影响与拱桥的脱空率、含钢率、桁高等参数有关。采用有限元分析方法对脱空状态下的钢管混凝土拱桥状态进行了具体分析，得到脱空对不同拱桥参数如刚度、稳定性及动力特性等的影响结果，为今后钢管混凝土拱桥的设计提供一定的理论参考。

| Abstract: | Effect of void on the stress characteristics of concrete filled steel tubular arch bridge relates pa- rameters of arch bridge, such as void ratio, steel ratio, truss higher parameters, and so on.Using finite ele- ment analysis method, the article analyzes the state of concrete filled steel tubular arch bridge in void con- dition, and get result about the effect of void on different parameters of concrete filled steel tubular arch bridge, such as stiffness, stability and dynamic characteristics. It will provide reference on theory for relat- ed design in future. |
