Abstract: An increasing number of high speed railways have been built in seasonally frozen soil regions of China. Engineering problems associated with frost heave, which seriously affects the engineering quality and operation safety, have received a generous concern and achieved significant research results. Based on the previous studies, in this paper, a summary is presented on frost heave characteristics and distribution in seasonally frozen soil regions with high speed railways, then the variations are analyzed of soil moisture and heat situation during freezing process of subgrades. The frost susceptibility is discussed of high speed rail railway filled of various fine content and under various water and temperature conditions. Finally, the existing anti-frost heave measures are classified and assessed according to their serviceability. Above all, a prospect of potential research directions about frost heave in high speed railway are presented, including new ideas for better interpreting the frost heave mechanisms and puts forward appropriate measures for mitigating frost heave deformation of high speed railway in seasonally frozen soil regions.

Key words: seasonally frozen soil, high speed railway, subgrade, frost heave, research progress, prospect
