郑西客运专线国内首次采用CRTSⅡ双块式无砟轨道,结合郑西客运专线CRTSⅡ型无砟轨道结构特点、设计方法,系统介绍了路基、桥梁及隧道地段无砟轨道结构设计、排水、过渡段及综合接地设计,为其他客运专线CRTSⅡ双块式无砟轨道结构设计提供了参考。
For the first time in China, the CRTS Ⅱ double-block ballastless track is used in the Zheng-Zheng Passenger Dedicated Line. Based on the structural features and design method of CRTS Ⅱ ballastless track for Zheng-Xi Passenger Dedicated Line, the structural design, drainage and transitional section of ballastless track for subgrade, bridge and tunnel are introduced systematically. And integrated grounding design for the other passenger dedicated CRTS Ⅱ double block ballastless track design provides a reference.
