Abstract

The article presents the results of experimental studies of the unfrozen water content (W_w) in frozen soils with different grain size distributions with a degree of peatification from 3 to 100% (in increments of 10%). The obtained patterns W_w = 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. The study primarily considers the patterns of moisture changes due to unfrozen water with a degree of peatification above 50%, when soils are referred to peat according to GOST 25 100–2020. The patterns of the change in W_w from the degree of peatification at fixed temperatures are given.
