Abstract
The thickness of the plastic zone in frozen soils, which is formed as a results of the thermal effect of the thaws bowl, is established. Its dependence on the initial temperature regime and properties of the soils is demonstrated, and settlements of the plastically frozen zone that forms beneath the thaw bowl are analyzed. Scientific observations confirming data derived from numerous investigations are addressed. The need to include the plastically frozen zone in the design scheme, and determine its settlements when frozen soils are used as foundation beds in accordance with principle II is established.
