Abstract : In the report calculated soil characteristics are established for their thawed state. However, the 'critical' period for frozen foundations and earth road beds is the period of thawing of the soils. The weakening of clayey ground during thawing and failure to consider this fact when planning and designing the foundations of structures and earth road beds are frequently the cause of their deformation, especially in deep freezing regions. In order to estimate the weakening of thawing clayey ground, the Novosibirsk branch of the All-Union Scientific Research Institute of Transportation Construction performed laboratory and field studies of the shear strength of these soils before freezing and after freezing and thawing. The characteristics of the investigated soils are presented. (Author)
