Using the probabilistic approach, authors consider the case of development of a dangerous geological phenomenon i.e. the large underground erosive channel, induced by a mechanical suffusion during construction of the pumped storage energy plant in Zagorsk (PSEP-2). Formation of the erosive channel has led to the formation of cavities with the diameter up to 10 metres in the middle and upper-quarternary, suffusion-unstable, the fluvial-and-glacial and lake-glacial deposits of the Moscow and Dnieper moraine. Thin deposits were the bearing basis of the concrete construction of the dam of PSEP-2 in Zagorsk. The lack of proper consideration of difficult engineering-and-geological conditions and the subsequent formation of emptiness has led to the unilateral draft of the building of PSEP-2 in Zagorsk. Draft of the building of PSEP-2 in Zagorsk has detained the start-up of the building into maintenance and has resulted in significant economic damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
