［摘要］南宁东站采用线上式高架候车的大型桥建合一铁路站房。其站台层被3条正线分成4部分，到发线采用普通混凝土框架结构体系，正线桥采用地道式框架桥，提高了出站层的建筑净空。高架候车层采用双向预应力混凝土框架梁，减轻了结构自重，并对应于正线桥的位置设置2道结构缝，有效地降低结构的温度作用。屋盖采用钢管混凝土柱支承的管桁架与网架相结合体系，结构布置安全、经济；而且结构和建筑形态、效果完全统一。天窗采用由钢梁和钢拉杆组成的屋架结构，结构受力合理又便于施工，实现结构与建筑的完美结合。结构计算与分析表明，结构体系传力明确，具有良好的经济性和抗震性能。

Abstract: As a large railway transportation hub, bridge-station combined structure with high elevated waiting hall is used to Nanning East Railway Station. 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
