广州南站(2×32+64+2×32)m双线V构连续梁设计

The Design of Guangzhou South Railway Station(2×32+64+2×32) m V Structure Double Line Continuous Beam

(2×32+64+2×32)m双线槽形V构连续梁是广州南站桥建合一结构体系中的轨道梁,是承载上部站房候车厅层(高程21 m层)的结构柱的受力构件和铁路运行的轨道梁(高程12 m层)及站台板梁横向支承的结构。着重介绍该V构连续梁(高程12 m层)与站房候车厅层(高程21 m层)及站台板梁的相互关联及受力状态、V构连续梁的结构构造、静力分析、局部分析、抗震分析等。最后对结构设计进行总结、提炼,为同类结构提供参考。

The （2 × 32＋64＋2×32） m double V-groove structure continuous beam is the track beam of the integrated bridge-building structure of Guangzhou south station,serving as the load bearing structure of the upper station waiting hall （21 m elevation layer） column,the railway track beam （the 12 m elevation layer） and the transverse supporting structure of the platform plate beam. This paper addresses the correlation and stress state, V-shape rigid frame continuous girder structure, static analysis, local analysis, seismic analysis with regard to the V structure continuous beam （ 12 m elevation layer） , the station waiting hall layer （21 m elevation layer ） and the platform plate beam. Finally, the structure design is summarized and refined, which may provide some reference for similar structures.
