Bondar M. Reduction of environmental danger by the use of industrial wastes for implementation of anti-landslide measures

In the dissertation research the actual scientific-practical task is solved: increase of level of ecological safety of the populated areas in conditions of development of landslide processes by realization of system of engineering anti-landslide measures. For the first time an environmental danger`s assessment from landslide processes` development in The Middle Dnipro Area was done, based on the monitoring of landslide processes and their both regional and local development risks. It gave us an opportunity to develop recommendations for an implementation of anti-landslide measures` applications in separate landslide areas of the region. These measures were also analyzed from the position of a reasonable application. The analysis of research development was conducted on landslide processes` problems alongside with an anti-landslide measures` application and both constructive and regional specifics in the anti-landslide measures` application. The prospects from using multi-tidal ash-slag waste TES as perspective materials for practical implementation of engineering anti-landslide measures were analyzed. For the first time an ash-slag components` element composition from multi-tidal wastes in Ladyzhynska TES was studied. It enabled us to assess a perspective from their application in an engineering anti-landslide measure`s implementation. Both theoretical grounds and an example of the general geofiltration model for predicting the change in the hydrogeological conditions of the investigated area`s practical implementation were given. Reasons that caused these modifications were in connection with the anti-slide measures` implementation: the location of solid walls under the foundations around the buildings` contour or an deep-immersion pile. Scientific value of the work lays in using the ash-slag wastes in thermal power plants for building the engineering anti-landslide structures, with the help of which an environmental danger`s minimization from landslide processes` development is obtained. Uncontrolled accumulation of ash-slag wastes from thermal power plant also causes considerable danger for the environment. Practical significance from the obtained results lays in an implementation of scientific studying results for environmental safety`s management in populated areas under conditions of landslide processes` development. The methodological bases of ecological safety in the conditions of development of exogeodynamic processes are considered. The proposed methodology of ecological hazard research from the development of exogenous geological processes, the structure of natural and man-made factors of origin and development of exogenous geological processes is considered. The classification of environmental hazards of the geological environment is presented. The proposed strategy for assessing the effectiveness of engineering measures to minimize environmental hazards from exogenous geological processes. The monitoring of the state of the geological environment of the Kyiv industrial and urban-agglomeration and the Middle Prednieper from the standpoint of the development of landslide processes has been carried out. The development of landslide processes in the city of Kyiv, on areas of the Kiev reservoir area, in the area of Kaniv reservoir is analyzed. The dynamics of development of landslides and degree of defeat by landslides of the territory are studied. The methods of engineering protection of anti-landslide measures processes and application of industrial waste for their realization are considered. The analysis of stability of the geological environment to natural, technogenic and natural-technogenic factors of landslide processes has been carried out. The prospect of the use of ash-slag mixes for the implementation of anti-landslide measures engineering measures is considered: in the composition for the construction of counterfoils holding prisms or retaining walls and the use of ashes for removal of soils. A theoretical substantiation and an example of the practical application of the general geophylographic model for predicting the change in the hydrogeological conditions of the investigated area in connection with the implementation of anti-slip measures - the location of solid walls under the foundations of the contour of buildings or deep-immersion piles.
