Abstract: | On the example of frozen soils and ice existing at temperatures close to the melting point, the existence of two mechanisms
(types) of destruction related to the phase transitions of water is shown. The first mechanism that operates near the melting
point is plastic destruction, it gradually converts an ice body into a liquid-like state. The second mechanism operating far
from the melting point is brittle destruction, disintegration into parts, with a slight preliminary deformation. For both
types of destruction equations of long-term strength and of the behavior of deformation in time have been obtained. |
