Test and numerical simulation on frost heave in frozen soils in intermittent freezing mode
In this paper, experimental research on the response of frost heave in intermittent freezing mode characterized by different frequencies and amplitudes was carried out in opening system, temperature distribution, temperature gradient and evolution of frost heave in the soil samples made up of Tibetan silty clay were acquired and analyzed. Based on frost heave model of coupled heat and moisture, compiled program to simulate the temperature distribution and evolution of frost heave in soil samples in opening system, the simulated results agreed well with the experimental values and showed that the continuous-intermittent freezing mode was effective for restraining the magnitude of frost heave, and the various responses of frost heave in frozen soils were caused by different intermittent freezing modes characterized by frequencies and amplitudes.
