摘要：

Heat and moisture transfer in unsaturated soil were studied. By analyzing the mechanism of heat and water transfer in unsaturated soil together with mass and energy conservation principles, the theoretical model of heat and water migration in unsaturated soil was established. Experimental study on heat and water transfer in sandy soil with air convection was carried out, and the temperature, volumetric water content and water evaporation intensity in varied air convection velocity were obtained by measurement and numerical simulation.
