Investigation of the Influence of the Physical Properties of Landfill Soils on the Stability of Slopes in the Context of Solving Civil Security Problems

Abstract

The paper presents the results of laboratory studies of the influence of the physical properties of landfill soils on the stability of slopes, namely, the determination of mechanical properties – the angle of internal friction, specific adhesion, and the shear angle of experimental landslide blocks under conditions of different humidity, density and temperature; determination of physical properties – humidity, temperature and density on the fact of shear of the experimental blocks, taking into account the gradual increase in humidity. The results of laboratory tests are processed using the classical statistical method. This made it possible to confirm the reliability of the mathematical model, which includes the solution of individual tasks for assessing the physical properties of landfill soils, and the corresponding methodology developed on its basis for preventing emergencies associated with shear of landfill soils at potentially hazardous burial sites for solid domestic waste.

Water Extracts from Waste Rocks of the Coal Industry of Chernvonograd Mining Area (Ukraine): Problems of Environmental Safety and Civil Protection

“…The results presented in the article are a contribution to the development of the theory of geochemistry of technogenesis and the theory of environmental safety, replenish the databases of pollutants that should be combined into a single database using new developments in information technologies [40,41]. In addition, the results of our research will be useful in designing new methods of coal mining and coal mining waste storage [42,43] and designing safety systems of man-made objects [44,45].…”

“…In the case of some other types of emergencies, the issue of their prevention or assessment may be even more complex, requiring additional determination of physical [9] or chemical [10,11] environmental parameters, which may occur in earthquakes or industrial accidents. A complication is also the need to involve third-party equipment, in particular, electrical monitoring and surveillance systems in case of prevention of terrorist emergencies [12].…”
