摘要
以湖南南县茅草街特大桥为例 ,讨论大跨度钢管混凝土拱桥施工阶段和运营阶段的弹性稳定和极限承载力。分析计算时 ,考虑了拱桥结构分阶段刚度变化、截面逐次形成以及构件的极限承载力等影响。
A discussion was presented of elastic stability and ultimate bearing capacity of long span steel tubular concrete arch bridge during construction and operation. In analysis and computation, the impact of the following factors was taken into consideration: rigidity variation of bridge structure at different stages; successive formation of section; and ultimate bearing capacity of structural members.
