Effect of dynamic action on compressibility of thawing sands
Conclusions 1. The compressibility of thawing sands under dynamic impact action exceeds the compressibility of thawed sands having the same initial density. 2. As the ice content decreases and the density and grain size increase, the compressibility of thawing soils under impact load action decreases. 3. The relation between the compressibility of a thawing sand and the vibration acceleration under impact action is nonlinear and is best approximated by a logarithmic function. 4. The method developed here for analysis of the settlements of thawing bases, taking into account the dynamic action is approximate and it can be recommended only for bases consisting of sands of massive cryogenic texture without appreciable ice lenses or inclusions.
