Effect of initial moisture content and soil type on permeability of frozen soil Item Info

The purpose of this thesis was to investigate the factors which affect the permeability of frozen soil, especially the effect of soil type and initial moisture content before the soil is frozen. This information is necessary to be able to predict when the possibility of frozen ground floods exists. The permeability of frozen soil columns was measured under isothermal conditions in the laboratory using air. The product of porosity and 1.0 minus the initial moisture content was deternined to be a significant parameter affecting the permeability to air. When this parameter is less than 0.13 the permeability approaches zero in all types of soils tested. Using certain critial values of the parameter would enable a person to predict when the possibility of frozen ground floods exists by taking soil samples in the field. The particular critical value of null(I-S) to be used for various soils should be investigated in field studies.
