Abstract The freeze-thaw action in seasonal frozen regions can lead to moisture migration in soil. When the static load is applied on the soil，the stress fields in soil change，and then the moisture contents and the pore water pressures change accordingly. The variations of pore water pressure and moisture in soil were studied with the model test under the freeze-thaw and static load actions. The test results indicate that the variation of pore water pressure is stable during the initial stage，then increases rapidly and finally varies cyclically in two cases with or without loading. The pore water pressure increases and the moisture content decreases with the depth of soil in the case without loading. Under the load condition，the pore water pressure and moisture content at the upper and the middle position of the soil body were greater than those at two sides of soil body. In a freeze-thaw cycle，the pore water pressure and moisture content increase with the temperature rising. The pore water pressure and moisture content change with temperature with a time delay.

Key words： soil mechanics freeze-thaw cycle load model test pore water pressure moisture content
