摘　　要：遵义至瓮安铁路上跨湘江为全线重点控制工程,介绍湘江特大桥主桥的桥位现状,为得到主桥合理桥式方案,根据桥位自然状况,提出两个可行的桥式方案,从结构受力、工程投资、施工控制、景观性等方面对两种方案综合比选,最终选择1-375 m上承式拱桥为推荐方案,为复杂山区铁路桥梁设计提供借鉴。The Main Bridge of Xiangjiang River Extra-long Bridge is the key project of the entire railway.This thesis introduces the conditions of the main bridge site. In order to select suitable bridge type,two feasible schemes of bridge type are proposed according to the natural conditions of the bridge site. This paper compares and analyzes of the two schemes in terms of investment scale,construction control and scenic effect. Finally,1-375 m deck arch bridge is selected as the recommended bridge type. This type of bridge may provide references for the design of complex mountain railway bridge.
