无碴轨道是保证高速铁路运行的一种轨道铺设形式,其铺设条件评估的重点是线下工程的沉降变形。郑西客运专线正是采用这种轨道铺设形式,要做好郑西客运专线施工期间的沉降观测,就必须对沉降观测资料进行分析,预测工后沉降,确定无碴轨道的铺设时间,确保无碴轨道结构的安全。
Ballastless track is a form of track laying to ensure the operation of high-speed railway. The emphasis of its laying conditions assessment is the settlement deformation of the line project. Zheng-Zheng Passenger Dedicated Line adopts this kind of track laying form. To do the settlement observation during the construction of Zheng-Xi Passenger Dedicated Line, it is necessary to analyze the settlement observation data, predict the post-construction settlement, determine the laying time of the ballastless track, Safety of ballasted track structures.
