中文摘要:

      桥上无缝线路的纵向力，由于梁轨相互作用，将通过桥跨结构传递到桥梁的墩台上。对桥墩进行强度检算和安全储备量分析，进而优化新建桥上无缝线路设计，使设计达到既安全又经济。

英文摘要:

      Due to the interaction between railway bridges and CWR, the longitudinal forces of CWR arepassed to the piers through the structure of the bridge. In this paper, the intensity of the piers is calculated and their safety reservation analyzed in order to gu
