摘　　要：铁路桥式站车站结构的横桥向宽度、竖向柱底反力值均显著大于区间桥梁结构。当车站及区间均采用无砟轨道时,车站结构与区间桥梁结构存在横桥向及竖向变形协调问题。基于新建某铁路桥式站的设计,对车站承轨层结构的横桥向及竖向变形进行分析计算,提出变形协调控制关键技术,为后续采用无砟轨道的铁路桥式站设计提供借鉴。The horizontal bridge width and vertical column base reaction force values of the railway bridge station structure are significantly larger than those of the bridge structure.When both the station and the section adopt ballastless tracks,the station structure and the section bridge structure will have coordination problems in the horizontal and vertical deformations.Based on the design of a newly built railway bridge station,we analyze and calculate the horizontal and vertical deformation of the station structure,and key technologies for deformation coordination control are proposed,which can provide reference for the design of railway bridge stations using ballastless tracks.
