摘　　要：以某一铁路斜拉桥为例,建立了斜索、桥塔、轨道、桥梁、墩台、基础为一体的三维有限元模型,并采用该模型分析了斜拉桥铺设无缝线路后钢轨纵向附加力分布规律,对无缝线路在斜拉桥上的铺设研究有重要的意义。Taking the railway cable-stayed bridge as an example, the paper establishes 3D finite element model by integrating with the cable, bridge tower, rail, bridge, pier and foundation, and analyzes additional longitudinal force distribution law of the steel rail track after paving joint-less track on the cable-stayed bridge, which has significant meaning for studying the jointless track paving on the cable-stayed bridge.

关 键 词：斜拉桥 无缝线路 纵向附加力 有限元模型
