Loss of bearing capacity of roads during thaw and debris flows in mountain permafrost: the same phenomenon.

Author(s) : DYSLI M.

Summary

The paper deals with the similitude between the loss of bearing capacity due to thawing in frost susceptible soils which form the subgrade of roads and railways and the formation of debris flows in mountain permafrost subjected to climatic warming. It is especially shown that, at the thermal level as well as at the mechanical level, the phenomenon is the same and that the latent heat of fusion of the ice play a major role. This explains the brutality of these two phenomena which are both destructive and costly.
