连盐铁路灌河特大桥正桥钢梁采用（120＋228＋120）m三跨连续刚桁柔拱一桁拱组合体系，揉合了拱桥和下承式桁梁桥2种桥梁造型，使整个桥体线型流畅、比例协调、受力合理。文章重点介绍了选择桥型所遵循的原则、正桥钢梁结构设计、结构静力分析、结构的关键构造、钢梁防腐涂装体系以及钢梁安装等。灌河特大桥的建造采用新结构、新材料、新工艺的“三新”技术，平顺的轨道支承结构为列车的运行提供了更为平稳、安全的保障。
連鹽鐵路灌河特大橋正橋鋼樑採用（120＋228＋120）m三跨連續剛桁柔拱一桁拱組閤體繫，揉閤瞭拱橋和下承式桁樑橋2種橋樑造型，使整箇橋體線型流暢、比例協調、受力閤理。文章重點介紹瞭選擇橋型所遵循的原則、正橋鋼樑結構設計、結構靜力分析、結構的關鍵構造、鋼樑防腐塗裝體繫以及鋼樑安裝等。灌河特大橋的建造採用新結構、新材料、新工藝的“三新”技術，平順的軌道支承結構為列車的運行提供瞭更為平穩、安全的保障。

The main bridge steel girder of Guanhe major bridge on Lianyungang-Yancheng Railway adopts (120 + 228 + 120) m three-span continuous rigid truss and flexible arch-truss-arch combined structural system, which combines the arch bridge and through truss, making the whole bridge graceful in line, coordinated in proportion and rational in stress. This paper presents principle of bridge type selection, design of the main bridge girder, analysis of static structure, key structure of framework, anti-corrosion coating system and girder erection, etc. Guanhe major bridge adopts new structure, new material and new process, the smooth track supporting structure provides more steady and safer guarantee for the train operation.
