| 摘 要： | 在几个工程实践的基础上,对钢管混凝土系杆拱桥的设计方法、刚度取值、稳定方面以及总体设计的一些主要参数做了一些探讨。提出对于钢管混凝土拱桥,采用钢筋混凝土的计算方法是比较恰当的;而对于中等跨径钢管混凝土拱桥的系杆安全系数选择则宜介于一般预应力构件与特大桥吊索之间。

| Abstract: | Based on the engineering practice, studies are carried out on some key parameters for the design method, value of rigidity, stability and overall design of the steel pipe reinforced concrete tied arch bridge, with proposals that the steel pipe reinforced concrete arch bridge be calculated in the same way as the steel bar reinforced concrete and that the safety factor of the tie bar on the medium span steel pipe reinforced concrete arch bridge be between that of general prestressed components and the extra large bridge suspender. |

| Keywords: | steel pipe reinforced concrete arch bridge method of calculation stability overall design |
