摘要
钢管混凝土拱桥可以通过拱肋侧倾来提高横向整体稳定性。本文利用有限元方法研究了钢管混凝土提篮拱桥的拱肋侧倾角对稳定性的影响,给出了拱肋的合理侧倾角。结果表明,在拱肋横向联系很强大的情况下,拱肋内倾对提高横向稳定性的作用不明显。
Concrete filled steel tube arch bridge can improve the lateral stability by sloping the arch rib.Using finite element method,the effect of sloping angle on stability is studied,and the reasonable sloping angle is given in this paper.The study also shows that the effect of sloping angle of arch rib on stability is little when the stiffness of the transverse beams is very large.
