[摘要]  新建的武汉火车站是特大型火车站，它将大跨结构、多层钢结构、桥梁结构融为一体。结合建筑特点对屋面与楼面结构体系进行了选择，并对主要结构的受力特点进行了分析。在屋面结构中，采用拱与网壳杂交的“拱-壳”组合体系，而拱与网壳采用V形撑进行连接。楼面结构与屋面结构的间接结合，降低了主要构件的受力。工程采用的结构体系对于其他大型公建，特别是大型高架车站具有很好的借鉴意义。

Abstract:  Wuhan railway station is combined with long span structure, multi-story structure and bridge structure. How to select the floor and roof structure system according to the architectural characteristic is presented. The structure characteristic of main elements is analyzed. In the roof, the "arclr shell" combinatorial system is adopted, the arch and the latticed shell is linked with the latticed shell by V branch. The inner force of main structure is reduced by the indirect combination of floor and roof structure. The structure system of the project can supply reference for bigscale publi works, especially for elevated railway station
