Abstract: Irreversible behavior of the ground or a rock mass encompasses both the transition of the ground over a peak strength and further development of the nonreversible movement and deformation. The irreversible ground movement is traditionally considered as the transition to chaos. However the moving ground passes through itself the energy of ground pressure, thermal energy, and exchanges by substances with surrounding rock mass. According to thermodynamics of irreversible processes, such a non-equilibrium ground behavior may create dissipative structures that are the embodiment of self-organization. The paper describes the results of the structures investigation, which have been unveiled with incremental fields of the irreversible ground movement during a landslide development and underground roadway maintenance. These structures were evolving from close interaction of the separate blocks or fragments of the ground and distant cooperation of the short-lived clusters that were periodically rearranging in time and space as the irreversible ground movement started and progressed. Extant techniques restrain basically one prevalent component of the irreversible ground movement. The other two collateral transversal components were usually ignored. However, blocking of these transverse components can prevent the development of a dangerous irreversible movement of the ground and a rock mass.
