LITHOSTATIC MECHANISM OF CRYOGENIC HEAVING FORMATION

Abstract
The existing views on the physical conditions of cryogenic heave of grounds are discussed. It is shown that it is necessary to clearly distinguish between two types of ground systems: closed and open. For the closed systems the accepted models are physically correct. However, they are not suitable for the open systems. The positive landforms of cryogenic heaving can rise by the Archimedean force due to the density difference between the thawed and frozen ground. Such a mechanism of swelling, considering the nature of the substrate in which it realizes, can be called lithostatic. The author worked out a theoretical framework including some mathematical assessments of the lithostatic mechanism. The appropriateness of the lithostatical concept is proved by the author's experiments, as well as by the actual data of other researchers. Lithostatic concept makes clear a number of peculiarities of cryogenic swellings, which previously had no strict physical explanation. Using thе lithostatic concept for the explanation of various phenomena in the formation of the forms of cryogenic relief could be useful both in scientific, and in practical terms.
