Abstract
One of the problems with high-speed tracks in service is the damage of their cement asphalt mortar layer. The development of cement asphalt mortar damage can lead to gradually failure of the slab s...
Highlights
A new type of slab track, the so-called China Railway Track System I (CRTS I), is developed and has been applied in the high-speed lines of Chongqing–Suining, Shijiazhuang–Taiyuan, Shanghai–Nanjing, and Harbin–Dalian railways in China.[1]
The developed model is to study the effect of the location of the damaged cement asphalt mortar (CAM) zone on the track dynamics
The following conclusions can be drawn: 1. When the vehicle passes over the damaged CAM zone, the dynamic responses of the track increase significantly and their maximum values appear in the middle of the damaged zone
Summary
A new type of slab track, the so-called China Railway Track System I (CRTS I), is developed and has been applied in the high-speed lines of Chongqing–Suining, Shijiazhuang–Taiyuan, Shanghai–Nanjing, and Harbin–Dalian railways in China.[1]. The influence of sizes and locations of the damaged CAM zone on the dynamic characteristics of wheel/rail contact force and the track displacement was not discussed.
