Characterization of the Physical Properties of Frozen Soil under Varying Ice Content

摘要

In the North Atlantic Treaty Organization Reference Mobility Model, the bearing capacity of frozen soils is a function of vehicle weight and frozen layer thickness. This relationship is based on the failure criteria of elastic plates extended to vehicle bearing capacity of ice sheets. In practice, this is found to be very conservative. A new study to investigate different approaches is underway. As part of this study, we examine how inherent soil physical properties change as a function of ice content, temperature, and engineering soil type. The final step will be to determine how these parameterizations affect the different bearing capacity formulations and to compare them to field data.
