Abstract：The simulation curve and test curve of frost heave are analyzed by using the theory of fractal geometry，and it is shown that the curve of frost heave is of self-comparability. At the same time，the function of temperature-time is set in order to obtain the relation rule between frost heave and time. Then，the relation curve of frost heave with time is fitted by using LHIFS and fractal interpolation. Thereby frost heave is predicted. At the same time，the result of imitation is contrasted with that of survey and calculation，which indicates that the result of fitting is stable and accurate. So a new prediction method is offered for frost heave.
