摘要
盐城特大桥主桥为(72+96+312+96+72)m五跨连续钢桁斜拉桥,是徐宿淮盐铁路的关键工程。论文重点阐述盐城特大桥方案选择、静力计算、结构分析、结构构造细节、钢梁防腐涂装体系和钢梁安装等。设计表明,盐城特大桥主桥结构受力明确,安装方案合理,具有较好的稳定性和经济性能。
Yancheng Extra-large Bridge is a continuous steel trussed cable-stayed bridge with five spans of（72＋96＋312＋96＋72）m, which is the key project in Xu-Su-Huai-Yan Railway. This thesis is going to stress the aspects of the project including type choosing, calculation of static force, analysis of structures, analysis of construction details, coating system for girders’ corrosion prevention, construction of girders, etc.The design of Yancheng Extra-large Bridge shows that this project has the structures with clear force-bearing and appropriate construction method, which offers the bridge good stability and economic features.
