摘要
研究了斜拉拱桥的力学特性以及与普通拱桥的内力分布差别,通过实例计算,得到了斜拉拱桥中斜拉索对拱结构内力良好的优化结果。通过该桥型与普通拱桥的对比研究及其扣索倾角这一参数的变化分析,给出其力学特性和经济性能,为这一新颖桥型的设计和方案选取提供参考依据。
This paper studies the mechanical behavior of cable-stayed arch bridge and the differences of internal force distribution between the bridge and normal arch bridge. Through analytical calculations, fairly good results of the internal force of the arch structure of the bridge optimized by the stay cables are obtained. By comparative studies of the bridge and the normal arch bridge, and by analysis of inclination angle parameter changes of the stay cables, the paper works out the mechanical behavior and economy of the bridge, which may serve as reference to the design and alterative selection of such new type of the bridge.
