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。
Nanning East Railway Station using an overhead line waiting to build a large railway station building a railway. The station floor is divided into 3 parts by 4 lines. The arrival line adopts the ordinary concrete frame structure system, and the main bridge adopts the tunnel bridge with the tunnel type to improve the clearance of the outbound story. The two-way prestressed concrete frame beams are used in the elevated waiting room to reduce the weight of the structure, and two structural joints are provided corresponding to the position of the main bridge to effectively reduce the temperature effect of the structure. The roof adopts the combination of pipe trusses and grids supported by concrete-filled steel tubular columns, and the structure is arranged safely and economically. Moreover, the structure and the building form are completely unified. The skylight adopts the roof structure composed of the steel beam and the steel pull rod, and the structure is reasonable in force and easy to construct so as to realize the perfect combination of the structure and the building. Structural calculation and analysis show that the structural system has clear force transmission, good economy and seismic performance.
