Abstract: Freezing tests in two different kinds of modes in the case of open system on 1D soil sample made of Tibetan silty clay are carried out, and the evolvement characteristics of the sample’s frost heave、temperature gradient field are obtained. Then according to the self-made programme based on the heat and moisture coupled frost heave model, aforementioned tests are simulated, and the result of simulation is quite consistent with the test result. Our research shows that frozen soil can make more frost heave easily under stepwise freezing modes. Our analysis makes it clear that the temperature gradient in frozen fringe with stepwise freezing mode is greater than that with continuous freezing mode.

Key words: freezing mode, frost heave, temperature gradient field
