- Abstract
Permeability tests on unsaturated frozen sand and gravel In artificial ground freezing applications, frozen saturated soil is assumed to be practically impervious. However, in the case of partial initial saturation, this is no longer the case. As part of a pilot study, permeability tests were carried out in the laboratory on cohesionless, loose, partially saturated, frozen soil samples. Mineral oil was used as the flow medium. Since no standardized apparatus exists, suitable experimental techniques and evaluation procedures had to be developed. The permeability of unfrozen, fully saturated soil was also determined for reference. Due to the loose packing and the low degree of saturation, the partially saturated soils exhibited a significant permeability, which is in the same order as the value of the corresponding water‐saturated, unfrozen soils.
