摘　　要：以蔡家嘉陵江大桥工程为例,对桥型进行研究,详细对比连续钢桁梁桥、拱桥、连续刚构混合梁桥在内的3种桥型可行方案,最终选择双塔斜拉桥方案。从整体布置、支承体系、主梁构造等方面对主桥设计展开探讨,可供相关人员参考。Taking Caijia Jialing River Bridge as an example,the bridge type is studied.The paper compares three feasible schemes of continuous steel truss bridge,arch bridge and continuous rigid-frame mixed girder bridge in detail,and finally chooses the scheme of twin-tower cable-stayed bridge.The design of the main bridge is discussed from the aspects of overall arrangement,supporting system and main girder structure,which can be used as reference for relevant personnel.
