| 摘 要： | 双曲拱桥最主要的受力构件是主拱圈,对其进行准确的受力分析是加固计算的关键。采用Midas软件,计算主跨50m双曲拱桥在各种荷载工况作用下的内力状况,通过内力计算结果找到结构破坏的原因,并根据其破坏状况确定相应的加固方案,这可为以后同类桥梁的加固设计提供参考依据。

| Abstract: | Major arch ring is the most important load-carrying structure of double-curved arch bridge.Force analysis of major arch ring is a key component of reinforcing computation.Using finite element software Midas,the distribution of internal forces under various of load cases of this doublecurved triangular arch whose span is fifty meters' long is calculated,thus finding out the destructive reason and determining the strengthening scheme.It can provide reference for similar engineerings of the same kind bridges. |
