Method for maintaining and handling railway ballastless track with frost heaving

The invention provides a method for maintaining and handling a railway ballastless track with frost heaving. The method includes the steps that geometric dimensions and linear position parameters of the railway ballastless track are obtained; the railway ballastless track is divided into frost heaving convex parts and frost heaving non-convex parts according to the geometric dimensions and linear position parameters of the railway ballastless track, the frost heaving convex parts are parts where protrusions are generated by the railway ballastless track in a frost heaving season, and the frost heaving non-convex parts are parts where protrusions are not generated by the railway ballastless track in the frost heaving season. According to the method, track elevations of the frost heaving non-convex parts are lifted or track elevations of the frost heaving convex parts are lowered before a roadbed frost heaving season, part of the track elevations of the frost heaving convex parts is preferably selected to be lowered in the roadbed frost heaving season, the elevation of the railway ballastless track can be adjusted accurately, the situation that the railway ballastless track unevenly deforms and the geometric dimensions and the parameters exceed specified values caused by the fact that a roadbed and a bridge and culvert foundation suffer from frost heaving is avoided, ride comfort of the railway ballastless track is improved, and comfort, stability and security are guaranteed when a train runs.
