| 摘 要： | 文章用当量压杆法推导出有横向联系肋拱桥的横向稳定临界荷载计算公式,并用能量法推导出了无横向联系肋拱桥的横向稳定临界荷载计算公式,同时考虑了拱肋的扭转效应和矢跨比效应。根据两种情况下的计算理论,对岳西天堂大桥进行横向稳定的分析,并得出相关结论。

| Abstract: | In this paper, the calculation formula of the transversely stable critical load of the rib arch bridge with transverse fixedness is deduced with the method of the equivalent compression bar. The calculation formula of the rib arch bridge without transverse fixedness is also deduced with the method of energy,and the effects of rise-to-span ratio and torsion of arch rib are considered in this calculation. Transversely stable analysis of Yuexi Heaven Bridge is carried out as an example,and some conclusions are got. |
