Abstract

The article presents the results of studies of self-organization of ice inclusions in the surface layer of frozen moisture-bearing rocks. Frosty weathering of rocks is determined by the formation of inhomogeneous stresses in the surface layer. They are due to the random nature of the appearance of crystallization centers and further inhomogeneous growth of crystalline (ice) formations. They are narrow, rectangular inclusions of fixed sizes for which solutions of the theory of elasticity are known. An original model of heat and mass transfer in the surface layer of a moisture-containing rock under the influence of variable temperatures with a period of ∼ 12 hours is used. The correlated arrangement of crystalline formations is determined by the process of minimizing the total elastic energy of the ensemble of ice formations depending on the angle of their mutual orientation.
