Abstract
The article discusses the results of experimental studies of the content of unfrozen water (Ww) in frozen soils of various granulometric composition with a degree of congestion from 3 to 100% (in increments of 10%). The obtained regularities Ww = f(t°C) are discussed. The role of the organic matter content in the formation of the phase composition of moisture in the temperature range from 0 to –18 °C. is estimated. Attention is focused on the consideration of the regularities of humidity changes due to unfrozen water with a degree of congestion above 50%, when soils according to GOST 25100-2020 are referred to peat. The regularities of the change in Ww from the degree of congestion at fixed temperatures are given.
