Formation of the unhomogeneity in pore space in the heavy swelling soils at the freezing-thawing

Radioisotopic procedure (Cl36) for studying variation of total hydraulic conductivity over the area in soil specimens of unbroken from used for characterization of pore space of soils during their swelling as well as freezing-defrosting that during freazing the proportion of rather big pores providing mainly filtration flow increased noticeably. The estimation of relaxation times dependent on the nature of ions in pore solution of the process was conducted. 23 refs., 6 figs
