Study on Mechanical Characteristics of Frost Heaving of Artificially Frozen Soil
, 2011 The impact of the cold-side temperature and moisture to frost heave were obtained by studying frost heaving test in open system. Frost heave ratio increased linearly with the decrease of cold-side temperature and moisture.
