In the seasonal frozen regions, the pore water pressures and water contents in soil are influenced by freeze-thaw cycles and external loads. In the model test, the sensors of pore water pressure and water content were used to measure the variations of pore water pressures and water contents of the loess under the freeze-thaw cycles and static load, and the changing process of pore water pressures and water contents at different depths of soil was obtained. The relationship between static stress and pore water pressures in the space was then examined. It is found that the pore water pressures of soil increased rapidly at the beginning of freeze-thaw and static load actions; and the pore water pressure then changed periodically with the temperature. In a freeze-thaw cycle, soil pore water pressure and moisture content increased with the increase of temperature, and decreased with the decrease of temperature. In addition, the pore-water pressure and moisture had hysteretic quality with the changing of temperature. Moreover, three concentrated areas of pore water pressure from the longitudinal section with the increasing number of freeze-thaw cycles were observed: one was directly below the loading position, and the other two were located between the edge of loading area and test chamber. Meanwhile, a high water content area below the static load and low water content areas on both sides of the static load were also found. Under the static load, the distribution of pore water pressure resembled the stress field calculated by the corner-points method. It is also considered that the present of these concentrated areas was related to the stress field of soils produced by the static load.
