| Abstract: | Reasons for the formation of frost heave are discussed, and a numerical method is explored which calculates frost heave of soil under one|dimensional condition. Interactions among water flow, heat transform and constrain pressure are considered in this method. The calculating results are compared with the observation results for the field. |
