The railway bridge structure floor is divided into 4 parts by 3 main line rails. Concrete frame structure system is adopted in the arrival and departure track, and tunnel type frame bridge is used in the main line track, which increases the headroom of the out station floor. The overhead waiting hall chooses two-way prestressed concrete beams, which reduces the weight of the structure. Two structural joints are set at the positions corresponding to the main line rails to reduce the temperature-induced internal forces. The combination structure of pipe truss and steel girder supported by concrete filled steel tubular column is used to the roof of the station, and the structure layout is economic and security. The roof truss structure which consists of steel bars and box beams is used to the skylight, this structure is simple and effectual, and easy for construction. The perfect combination of architecture and structure is realized too. Analysis and calculation indicate that the whole structure has good economy and seismic performance.Keywords: bridge-station combined structure; prestressed concrete beam; concrete filled steel tubular column; pipe truss structure; steel bar作者簡介：邱劍，教授級高級工程師，一級注冊結構工程師，Email：21244113@qq.com。參考文獻［1］邱劍,溫四清,熊巍,等.貴陽北站站房結構設計［J］.建筑結構, 2012,42(9)：1-5.［2］TB 10002 1—2005鐵路橋涵設計基本規(guī)范［S］.北京：中國鐵道出版社，2008.［3］TB 10002 3—2005鐵路橋涵鋼筋混凝土和預應力混凝土結構設計規(guī)范［S］.北京：中國鐵道出版社，2007.［4］GB 50011—2001建筑抗震設計規(guī)范［S］.2008年版.北京：中國建筑工業(yè)出版社，2008.［5］GB 50111—2006鐵路工程抗震設計規(guī)范［S］.北京：中國計劃出版社，2006.
