摘　　要：随着高速铁路的发展,“站桥合一”铁路站房结构体系应用越来越广泛。本文以丰台火车站中央站房为例,分别利用房建专业和桥梁专业有限元分析软件建立了空间结构模型,对承受火车荷载的轨道层结构进行了分析,研究了列车荷载在静力加载和影响线加载两种模式下结构的受力特征,为以后类似工程设计提供参考依据。With the development of high-speed railway,the"station-bridge"railway station is more and more widely used.Taking the central part of Fengtai Railway Station as an example,a spatial structure model is established by using the finite element analysis software of the house construction and bridge professional,and a preliminary analysis of the track layer structure bearing the train load is carried out,and the train load in static loading is analyzed.And the force characteristics of the structure under the two modes of influence line loading are studied,it can provide reference for similar engineering design in the future.
