| Comment |
Thaw weakening, although generally used with respect to the thawing of seasonally frozen ground when melting of ice lenses and pore ice occurs, is equally applicable to thawing of ice-bearing and ice-rich permafrost. The usual effects of thaw weakening are a significant decrease in bearing capacity and an increase in stability problems (e.g., on road embankments, natural slopes, etc.).
