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。
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.
