Unfrozen water contents of undisturbed and remolded Alaskan silt
AbstractUnfrozen water content as a function of temperature was measured in the laboratory using pulsed nuclear magnetic resonance (PNMR) for sixteen undisturbed frozen cores acquired from the Northwest Alaska Pipeline Company Chilled Gas Test Facility. The cores were then remolded and brought to their original densities and water contents, and unfrozen water content as a function of temperature was again measured over three warming and cooling cycles. It was found that differences in unfrozen water contents between the undisturbed warming and cooling curves depended upon relative degree of saturation and its effect on soil structure. Only slight changes occurred during the three warming curves of the remolded soil, indicating minor freezing and thawing consequences on the soil structure.
