Study of Structural-Geological Conditions of Landslide Processes Forming and Development of an Example of Odesa Portside Plant Territory (Ukraine)

Анотація
Purpose of the work has been to reveal tectonic discreteness and assess its influence on development of deformation and displacement of rock in landslide slope on an example of Odesa Portside Plant territory. Methodology. Methodology of the data analysis and processing included determination of magnitude and direction of displacements, deformations and their derivatives, as well as cartographic modelling of the parameters obtained. Results. Based on the results of cartographic modelling performed using the data from geological drilling and geodetic monitoring, locations and typical strikes of zones of current engineering–geodynamic activeness have been established. Directions of displacement traces are controlled by diagonal directions characteristic of geological structure of the area. Conclusions. Spatial and temporal regularities of the deformations and landslide displacements forming and development are subordinated to structural and geological features of Odesa Portside Plant territory. The main reason of activation of deformation and landslide processes is hierarchic-block structure of the territory characterised by continuous and differentiated character of movement of geo-blocks of different order. Due to complicated spatial character of faults systems in rock mass and kinematic peculiarities of geo-deformation processes, they are to be considered in designing and building of constructions, organization and implementation of engineering-geodynamic monitoring.
