Abstract: Abstract: Currently freezing method for its reliable sealing water, small disturbance to the surrounding environment, adaptability and other characteristics are widely used in mine construction, subway stations, underwater excavation and other projects. But the present research on frost heaving characteristics of soil was largely confined to the temperature, and the moisture. While the soil frost heave is the result of interaction with temperature field, moisture field and stress field. The study of the three fields’ mutual variation is not enough. In this paper four sets of experiments carried out at different cold junction temperature, high load conditions using single factor orthogonal experiment with WDC-100 type microcomputer control multifunction frozen soil compression testing machine developed by Anhui University of Science & Technology. we got the variation of the temperature field, the moisture field, and the deformation. This Provides necessary theoretical guidance for the future construction.
