“…In the experiment heave took place even during the first winter when the water content of the soil was very low. No dry and saturated parallel exists in our experiment for assessment of the importance of water content in the soil, but single other observations indicate that there can be heave also when the soil is unsaturated (Pissart et al, 1981;Viklander and Eigenbrod, 2000;Coussy, 2005;Li et al 2008).…”

“…In both cases H 2 O would migrate to another area owing to a temperature gradient, air is pushed out, and the local ice content increases (cf. Li et al, 2008). We propose that both mechanisms of transfer could be active so that heave is the result of vapour movement toward a freezing plane resulting in ice accumulation there.…”

“…Corte (1961) found vertical sorting in saturated sandy gravel without particles b0.02 mm and with only 14% b 0.074 mm during cyclic freeze point passages, and Li et al (2008) found displacement in unsaturated gravel over clay in a road construction. Gozdzik and French (2004) were puzzled by apparent upfreezing of 5-20 cm large and irregularly shaped stones in aeolian sand in Poland with the maximum upward movement being more than 1 m above the original stone horizon in the formerly presumably wettest part of their area.…”

“…In this case sediment was thought to enter beneath the stones during thaw. Corte (1961) reported vertical sorting in well-sorted sediments without particles finer than 0.02 mm; Li et al (2008) found movement in gravel over clay; and Gozdzik and French (2004) describe an example with stones that appear to have moved upward in aeolian sand.…”

“…Listed in the references are papers essential in understanding the long-lasting discussion devoted to rock glaciers. A particularly peculiar concept has recently appeared in permafrost studies, as well as in the context of research on rock glaciers: numerical modeling of the four-phase interaction between solids, water, ice and air [81][82][83]. Although ice is a phenomenon in some ways peculiar, there is no reason to treat it as a fourth phase and thus exclude it from the set of solid bodies.…”

Since Earth sciences have undertaken studies of other celestial bodies, its various fields have moved beyond the scope of study assigned to them by name. Interest in space makes it necessary to abandon research geocentrism and reverse relations when comparing the structure of the Earth with other celestial bodies. As an exceptional place in the universe, it should not be the Earth which constitutes a reference point, especially in cryospheric research, but rather the other celestial bodies of our planetary system. This approach, referred to as "Spatial Uniformitarianism," is the basis for determining the place of ice in the environment and for assigning it to the lithosphere. Ice can be penetrated by frost just as other minerals and rocks, so the occurrence of permafrost may yet be attributed to glaciers and ice-caps. In the article, the occurrence of glacial permafrost has been worked out on the basis of a thermal classification of glaciers with a thorough understanding of the phenomenon. This allows us to specify permafrost's presence beneath glaciers and ice-caps, a concept which had been needlessly vague. Further, by considering rock glaciers as a mixture of two types of rocks, and by understanding the importance of movement in their evolution, we are now closer to fruitfully determining their role in the environment, their geomorphological significance.

This study proposes a novel framework for ice‐rich saturated porous media using the phase‐field method (PFM) coupled with a thermo‐hydro‐mechanical (THM) formulation. By incorporating the PFM and THM approaches based on the continuum theory, we focus on the mechanical responses of fully saturated porous media under freeze‐thaw conditions. The phase transition between liquid water and crystalline ice can be explicitly expressed as captured by evaluating the internal energy and implementing thermal, mechanical, and hydraulic couplings at a diffused interface using PFM. Accurately modeling the coupled mechanical behaviors of ice and soil presents significant challenges. Therefore, in previous numerical frameworks, ad hoc constitutive models were adopted to phenomenologically estimate the overall behavior of frozen soil. To address this, we employ a method that differentiates between the kinematics of the solid and ice constituents, enabling our framework to accommodate distinct constitutive models for each constituent. Within this framework, we naturally introduce anisotropy of frozen soil as it undergoes the freezing process by integrating a transversely isotropic plastic constitutive model for ice. We illustrate the capabilities of our proposed approach through numerical examples, demonstrating its effectiveness in modeling the phase transition process and revealing the overall anisotropic responses of frozen soil.
