Prediction of emergency situations in ground surface constructions of slimmers
Keywords:sludge dump, hydrodynamic accident, probability, retaining structure, sludge, coefficient of proportionality, stability criterion, normal retaining level
Purpose. Proportionality coefficients kpr for different types of dams are obtained, which allow taking into account the presence of surfactants in the liquid during the filtration calculations. The purpose of the work is to refine the indicators that allow an objective assessment of the risk of emergencies on the retaining structures of the slurry storage facilities of the Republic of Belarus.
Methods. The data of field and experimental studies of the author and the results of their statistical processing, as well as theoretical studies on the development of indicators of the stability of structures are used in the work.
Findings. As a result of the research, scenarios for the development of possible emergency situations at the hydraulic structures of the slurry storage facilities of the Republic of Belarus were established, and a risk calculation for each of the reasons given for the occurrence of hydrodynamic accidents on this type of structures was performed.
Application field of research. The developed methodical approaches to assessing the risk of territories can be used for other risky processes of a technogenic nature. Cоnclusions. The results of the assessment of the risk of emergencies in the sludge dumps of Belarus, taking into account the updated data, are of practical importance for the determination of management decisions and technical measures to prevent the occurrence of hydrodynamic accidents in this type of facilities and minimize their consequences.
