为满足武广铁路客运专线高平顺性、安全性和舒适度的要求,为达到无砟轨道路基工后沉降、强度、刚度以及列车高速运行及自然条件下长期稳定的技术标准,为减小或避免由于不同线下基础刚度不同对列车高速运行时平顺性和舒适度的影响,实现不同形式过渡段刚度与变形的均匀过渡,在不同构筑物连接处设置了不同形式的过渡段,以涵路过渡段为例,对不同形式过渡段施工技术进行总结。 In order to meet the high ride comfort, safety and comfort requirements of Wuhan-Guangzhou Passenger Dedicated Line, in order to achieve the post-construction settlement, strength and stiffness of ballastless track subgrade and the long-term stable technical standards under high speed and natural conditions, Avoiding the influence of the different base stiffness on the ride comfort and comfort at high speed and realizing the uniform transition of the stiffness and deformation in different forms of transitional sections. Different types of transitional sections are arranged at the connecting parts of different structures, Section, for example, summarizes the different sections of transitional section construction technology.
