| 摘 要： | 桥墩纵向水平线刚度是桥梁和无缝线路设计的关键技术参数,桥上无缝线路钢轨与墩台纵向力的分配以及梁、轨位移的大小很大程度上取决于桥墩纵向水平线刚度。结合工程实际,以客运专线常见的60 m 100 m 60m连续梁为例,分析桥墩纵向线刚度对钢轨、墩台纵向力及梁、轨位移的影响规律。

| Abstract: | The longitudinal of pier is a key parameter in the design of the bridge and CWR.The distribution of longitudinal force between the rail and the pier,to a great extent,depends on the longitudinal of piers.So does the displacement of girder and rail.Based on engineering practice and taking the common 60 m 100 m 60 m continuous beam as an example,this paper analyses how the longitudinal rigidity impacts the longitudinal force of the rail and pier as well as the displacement of girder. |
