Abstract:

The stability of soil masses is determined by their filtration qualities and specific conditions of slope flooding caused by the freeze-thaw cycles. The stability of the seasonally thawed layer on the slopes formed of silty sands and sandy loams is usually disrupted during prolonged rains. The loams and clays start to move even without atmospheric precipitation, owing to the ground water forming during thawing of interbeddings of segregated ice. Here the typical conditions for the stability of wet soils lying on the surface of frozen ground are examined.
