Abstract

The aim of this work was identifying of dissipative structures as a product of the ground surface irreversible movement during a landslide development. A complex methodology has been used. Ground has been considered as an open thermodynamic system. It dissipates ground pressure energy and potential energy of the irreversibly sliding body along the gravity gradient. The author of this paper used geodetic monitoring, statistical analysis, and computing geometry for investigation of movement kinematics. Results. It was found that in the ground, which transferred over peak strength of the rock, dissipative structures emerge due to short interaction of the rock fragments and distant cooperation of rock clusters. This self-organization can be detected by monitoring of incremental movements having the magnitude from 2 to 10 standard errors of displacement measurement. Positions of centers of the clusters are determined by K-means clustering, and boundaries of these clusters may be outlined by Voronoi diagram in Euclid space. This facilitated unveiling of dissipative structures and developing of a new approach to provide stability of the ground. The main principle uses restriction of the three translational and three rotational degrees of freedom for the ground, which transferred over peak strength. Novelty. It was determined for the first time that the dissipative structures of the ground, which disperse ground pressure energy, are altered discontinuously due to their bifurcation. These structures have the patterns such as differently oriented irreversible moves of short-living ground clusters and domains, what provides accumulation of degrees of freedom for the development of the irreversible movements and deformation. It was for the first time when K-means clustering and Voronoi diagrams in Euclid space have been employed to detect the ground clusters, and short interaction of the ground fragments and long cooperation of the clusters were identified. Practical implementation of this novelty was used for the development of a new approach when the landslides are stabilized with the restriction all the degrees of freedom both translational and rotational.
