STABILITY OF THAWING SLOPES: FIELD AND THEORETICAL INVESTIGATIONS

Stability analyses of thawing slopes in cohesive soils are examined. On the basis of field investigations it was found that current methods which explain instabilities in thawing slopes are not correct in assuming the failing mass as a continuous and rigid translational block. Instead the structure of the failing mass was recorded to be composed of a deformable mixture of soil lumps and muddy water, the product of the thawing of a reticulate ice vein network subdividing the previously frozen soil into irregular blocks. A theoretical approach of stability analysis based on the particulate structure of the failing thawing slopes is presented. (TRRL)
