高速铁路桥上无缝道岔的轨道、桥梁设计,目前已有一些研究成果,但仍然是一个难点。文章介绍了厦深客运专线韩江特大桥大跨连续梁上铺设30号无缝道岔的设计,进行了岔-梁-墩的纵向相互作用分析,作为无缝线路及桥梁墩台设计的依据;桥梁竖向相对变形分析,确定道岔和桥梁的合理相对位置关系;车-岔-桥的耦合动力学分析,进行列车运行及结构的安全性和乘坐舒适性评价。
There are some achievements in the design of the track and bridge of the seamless turnout on the high-speed railway bridge, but it is still a difficult point. This paper introduces the design of the 30 # turnout on the long-span continuous beam of the Hanjiang Special Bridge in Xiamen-Shenzhen Passenger Dedicated Railway, and carries out the longitudinal interaction analysis of the fork-beam-pier as the basis for the design of the seamless railway and bridge pier ; Vertical relative deformation analysis of bridge to determine the reasonable relative position of turnout and bridge; coupling-dynamics analysis of car-turnout-bridge to evaluate the safety of train operation and structure and evaluation of ride comfort.
