Résumé

Research on frost-heave characteristics of soil should be done under the condition of low temperature. The experiment and analysis of frozen soil should be simulated just like actual heat exchange in nature. The design of a lab for low temperature frozen soil is followed by this principle. The structure of lab is a foundation pit of about 27 m3, including direct and indirect refrigeration systems. In direct refrigeration systems, the temperature of air in the foundation pit could be adjusted from 10 to -40°C. And in indirect refrigeration systems, the temperature of cycle salt liquor in brine coil could achieve -15°C. This lab could be used to simulate the freeze-thaw cycles of soil in nature. Temperature field and velocity field characteristic of the foundation pit are also analysed in this paper.
