Description
Summary:The scientific study of soil freezing and ice segregation began in the early 1900s. By the 1930s researchers (Taber 1930, Beskow 1935) had already found that ice segregation and the resultant frost heave are caused not only by freezing of in-situ water, but also by freezing of water transported toward a freezing front from the unfrozen part of the soil. The understanding gained in the 1930s was largely qualitative. However, the transport of water was already identified as one of major issues in the study of soil freezing. The problem has attracted the attention of many researchers (see Nakano 1991). The main constituents of saturated, frozen, and fine-grained soils are a solid porous matrix of soil particles and ice, and water in the liquid phase called unfrozen water. The physical properties of all constituents except unfrozen water are well understood. It is generally understood that the transport of water in frozen soils is mainly caused by the movement of unfrozen water and that unfrozen water exists in small spaces surrounded with surfaces of soil particles and ice. Heaving during freezing is not limited to water in soil systems. It occurs with benzene or nitrobenzene in soils (Taber 1930), water in various powder materials including hydrophobic carborundum (Horiguchi 1977), liquid helium in porous glasses (Hiroi et al. 1989), water in hydrophobic silicon-coated glass beads (Sage and Porebska 1993), and water in porous rocks (Miyata et al. 1994).
