针对桥上无缝线路纵向力的传递特点,运用线桥墩一体化计算分析模型,对64 m简支梁桥上无缝线路纵向力及梁轨的快速相对位移进行计算分析,提出了墩顶纵向水平线刚度的最小值,以指导大跨度简支梁桥上无缝线路设计。
In view of the transfer characteristic of longitudinal force of CWR on bridge, by using the integrated calculation and analysis model of bridge piers, the longitudinal force of CWR and the fast relative displacement of beam and rail on 64 m simply supported girder bridge are calculated and analyzed. The minimum value of top longitudinal horizontal stiffness to guide the design of CWR on long-span simple-supported beam bridge.
