针对石太线波浪磨耗形成机理进行探讨，认为在列车荷载作用下，钢轨内残余应力变化使轨头表面产生塑性流动及接触疲劳强度不足，导致波磨的形成。
Aiming at the formation mechanism of wave wear in Shitai line, it is considered that under the train load, the residual stress change in the track causes plastic flow on the head surface and insufficient contact fatigue strength, resulting in the formation of wave grinding.
