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.

泥炭化效应对不同粒度分布冻土中水相组成的实验评估

摘要本文介绍了对泥炭化程度在 3% 到 100% 之间（以 10% 为增量）、具有不同粒度分布的冻土中未冻结含水量（Ww）的实验研究结果。本文讨论了所获得的 Ww = f(t °C) 模式。估计了有机质含量在 0 至 -18°C 温度范围内形成水分相组成中的作用。研究主要考虑了泥炭化程度超过 50%（根据 GOST 25 100-2020 标准，土壤属于泥炭）的未冻水导致的水分变化规律。研究给出了在固定温度下，Ww 随泥炭化程度变化的规律。
