| 摘 要： | 针对城市轨道交通高架桥的具体结构形式,建立了考虑后继结构影响的城市轨道交通高架桥梁轨相互作用有限元计算模型.计算分析了某典型城市轨道交通高架桥的无缝线路纵向附加力,并对城市轨道交通高架桥长钢轨纵向水平力的合理计算模型进行探讨.研究结果表明,所建立的梁轨相互作用计算模型较传统的干线铁路桥无缝线路纵向附加力计算模型更能反映城市轨道交通高架桥的结构特征,其计算结果也更为合理.

| Abstract: | A finite element mechanics model is set up to calculate the additional longitudinal force transmission between the continuous welded rails and CWR viaduct,the continuous welded rail's longitudinal constraint effect on the bridge is analyzed according to the practical structure of viaduct in urban mass transit,and the additional longitudinal force of a typical CWR viaduct is calculated.This mechanics model for analyzing girder-rail interaction is considered reasonable,and the result of this research shows that the mechanics model for calculating the additional longitudinal force transmission between the continuous welded rails and CWR viaduct could reflect more structural features than the traditional calculation model. |
