摘要
该文以孙家凹桥为背景,讨论了上承式单肋拱桥的构造特点,研究了钢管混凝土拱肋刚度计算方法以及拱肋填充混凝土程度对其稳定特性的影响,得出结论,可为今后该类桥型的设计提供参考。
Taking a concave bridge in Sunjia as the background, the article discusses the construc- tion characteristics of deck single- rib arch bridge, studies the rigidity calculation method of steel- pipe concrete arch rib and the influence of filling concrete level into arch rib on its stabilizing characteristics, and gives the conclusion able to provide the reference for the design of this kind of bridge in the future.
