Stability of Soil Masses in Cold Regions
A soil mass located beneath a sloping ground surface has a tendency to move downward and outward under the influence of gravity. This moving mass may proceed by flowing, sliding, falling, or by a combination of these processes. Movement is counteracted by the soil shearing resistance, which can be mobilized along a potential failure surface. Materials involved in the movement may consist of naturally deposited soil (frozen or unfrozen), human-made fills, or a combination of both. The types and processes of slope movement in unfrozen soils have been identified and classified by Varnes (1978). Methods of stability analysis for various slope movements in unfrozen materials were reviewed by Morgenstern and Sangrey (1978).
