城市轨道交通由于运营时间长，钢轨磨损程度严重，特别是曲线地段钢轨，造成列车行驶颠婆，降低了旅客乘车的舒适度，为了消除列车运营安全需对磨损较严重长钢轨更换。
目前更换长钢轨采用简易门式支架或者人工将提前备好的钢轨替换磨损钢轨，但是这种城市轨道交通长钢轨更换施工是在列车停运后，有限的时间窗口内完成更换，时间短、施工工序繁杂、安全隐患高，长钢轨更换采用人工对新旧钢轨替换的方法实现，主要采用逐段拨入替换施工方法，拨入时均采用人工杠杆的方式进行拨入，一处拨入后再进行下一点的拨入，每次拨入为20m左右，100m长钢轨拨入工作需分四次完成。长钢轨更换时，考虑到安全性、时间性，防止拨入钢轨造成人员的伤害，长钢轨更换施工过程内容繁多、工序复杂、施工周期长、安全隐患大、施工周期长。
针对上述问题，目前国内关于城市轨道交通长钢轨更换技术还没有一套成熟的理念及路线，为解决以上长钢轨更换问题，填补国内长钢轨更换技术的难 题，需对现有长钢轨更换技术进行研究，使长钢轨更换技术施工效率、精度均满足要求。
