广州南站(2×32+64+2×32)m双线V构连续梁设计

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

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