Abstract: Main research achievements in freeze-thaw erosion home and abroad are summarized in this paper. First, the research category of freeze-thaw is discussed and its definition is crystallized. Second, main achievements in the freeze-thaw research are introduced and the changes of the property of soil and the soil erodibility affected by freeze-thaw are analyzed . The prediction model and the prevention and cure technique for freeze-thaw erosion are introduced. Finally, the tentative plan on freeze-thaw erosion research in china in the future period is proposed combining with the actual condition of this field in China.
