Stability of Flysch Rock Masses under Explosive Loading: A Review
Abstract
Purpose. To systematize current scientific approaches to assessing the stability of flysch rock masses under explosive loading and to determine their applicability to civil protection tasks.
Method. The study employs analysis and synthesis of scientific sources, comparative geomechanical analysis, a taxonomic approach to the classification of results, and inductive generalization. The source base consists of international scientific publications selected according to relevant thematic criteria.
Findings. The regularities of the mechanical behavior of flysch rock masses are generalized, taking into account their heterogeneity, anisotropy, and structural disturbance. The decisive role of the ratio of layers with different strength and moisture conditions in the formation of damage zones is established. It is shown that existing strength assessment approaches are primarily based on studies of industrial explosions, which imposes limitations on their application to the analysis of explosions of military origin.
Practical Implications. The obtained generalizations can be used for preliminary hazard assessment, zoning of territories according to risk levels, and decision-making support within the civil protection system. It is proposed to consider uncertainties and apply conservative approaches when assessing the consequences of explosive impacts.
Originality/value. The study combines geomechanical analysis with civil protection tasks, emphasizing the adaptation of existing scientific approaches to conditions of military impacts, which is novel for this research field.
Limitations/Future research. The limitations are related to the lack of field data on the effects of military explosions on flysch rock masses, which determines the need for further experimental and field studies.
Paper type: Review.
