Abstract
The object of research is the landslide hazard control of natural and man-made slopes, as a factor in environmental safety and stability of geomechanical systems. One of the problematic aspects in solving this scientific problem is the lack of an integrated approach in the study of landslides and insufficient laboratory studies of the physicomechanical properties of soft loamy rocks and soils. For a possible forecasting and control of the landslide hazard, a combination of analytical and laboratory studies, methods of numerical modeling of the stability of the slopes is necessary, and is used in the study.The 5-level evaluation landslide hazard of the natural and man-made slopes to control their stability is substantiated. Landslide hazard scale allows to reliably forecast the geomechanical state of the rock massif depending on the values of the slope stability factor in changing geoclimatic conditions and substantiate effective engineering measures for protection against landslides. Landslide hazard classification of natural slopes according to the value of safety factors is proposed. It can be used to evaluate the sustainability of man-made slopes of solid and bulk rocks, and to forecast the environmental hazard from landslides as a result of emergency situations.A structural-logical scheme for the landslide hazard control at the regional and local levels is based on modern methodological approaches regarding the evaluation and forecasting of the stability of natural and man-made slopes. Thanks to the use of an integrated approach for evaluating the stability and safety of the slopes, it is possible to scientifically-based monitoring of these geo-features.The use of the proposed landslide hazard control system allows justifying the stable parameters of geotechnical objects (man-made slopes) during the open development of minerals with due regard for geometrical parameters, physical and mechanical characteristics, flooding of the rock mass and external loads. Using an integrated approach for natural slope landscapes is an effective tool for determining the conditions of landslides.
Highlights
Landslide hazard is an important component of the ecological safety of territories, including man-made and geomechanics of soils and soft rocks, both at the regional and local levels.Natural and man-made slopes are almost always pre sent in different areas, are sources of potential environ mental or technological hazards, emergency or catastrophe
Favorable conditions for the activation of landslides have developed within the built-up urban areas of Vinnytsia, Dnipro petrovsk, Donetsk, Zakarpattia, Ivano-Frankivsk, Kyiv, Luhansk, Odesa, Kharkiv, Chernivtsi and other regions of Ukraine
For natural slope landscapes using an integrated approach is an effective tool for determining the conditions of landslides
Summary
Landslide hazard is an important component of the ecological safety of territories, including man-made and geomechanics of soils and soft rocks, both at the regional and local levels. Taking into account global and regional climate change trends, the intensity of landslide hazard with corresponding ecological consequences in natural slope landscapes and in the technical system with complex or artificially created relief is growing. The main factors influencing the stability of natural and man-made slopes are the climatic and hydrogeological indicators of the territory, in particular, the amount of precipitation and water saturation of mainly soft loamy rocks, as well as their geomechanical properties. About 23 thousand landslides have been recorded on the territory of Ukraine and their number is constantly growing due to over-wetting of the upper layers of unstable loamy, including loess soils [2].
