| 摘 要： | 该文以大跨度钢管混凝土桁架拱桥为背景分析了时变对拱肋结构力学状态的影响,结果表明时变对拱肋内力影响较小,而对应力影响很大,设计时必须考虑时变带来的应力重分布效应。

| Abstract: | Taking the large-span steel pipe concrete truss arched bridge as the background, the article analyzes the influence of the timing variation on the arch rib structural mechanics status. The result makes clearly that the influence of the timing variation on the inner force of the arch rib is smaller, but is very large on the stress. It must be to consider the stress great distribution effect brought by the timing variation. |
