摘　　要：随着高速铁路的快速发展,高架车站以其在优化站场布置、节约空间等方面的优势,开始被广泛采用。以京沪高速铁路天津南站站台梁为背景,对高架车站如何与桥梁设计相结合这一课题进行了深入研究。天津南站站台梁采用双层站台梁,由上层辅梁和下层主梁组成,采用有限元程序建立上层辅梁杆系模型和下层主梁实体模型,对站台梁进行结构尺寸比选、结构受力分析及施工步骤研究。通过计算分析,确定了本梁的结构尺寸和钢束形式。该桥采用平行施工、压重等措施,既保证了结构安全,又保证了施工工期。As the rapid development of high-speed railway,the viaduct stations are widely used because of their superiorities such as land saving as well as arrangement optimizing on station and yard.This article takes the station platform beam of Tianjin South Railway Station in Beijing-Shanghai High-speed Railway as an example to discuss how to combine the viaduct station design with the bridge design.Tianjin South Railway Station adopts double-deck station platform beams which consist of an assistant beam at the upper floor and a main beam at the lower floor.This article adopts finite element program to establish the models of the assistant beam and main beam,compares and chooses the structure sizes,analyzes the structure forces and construction procedures.Via calculation and analysis,this article makes clear the structure sizes and steel tendon arrangements.In addition,parallel construction method and ballast method as well as other measures are used in the construction process of this viaduct bridge so as to ensure the structure safety and construction schedule.
