Introduction Soil freezing and thawing have a harmful impacton roads and buildings in cold regions. For example,frost heave and thawing settlement lead to cracks, set-tlement and structure breaking. A number ofreports[1-3]indicated that the frost heave induced bywater transfer could exceed the volume of water chan-ges because of water freezing in the cells. The mainmodels for coupled heat and moisture transfer infreezing soil are hydrodynamic models and rigid icemodels[1,2]. Though the hydrod… 相似文献
