IMPACT FORECAST OF EMERGENCY SITUATIONS’ DANGEROUS FACTORS ON TECHNOSPHERE OBJECTS
The authors present a variant of a predictive solution for the state of the technosphere objects when exposed to dangerous exogenous geological processes that can be triggered by both natural and man-made flooding. It is proposed to use a complex R-indicator, which is a linear combination of partial criteria (R1, R2, R3, R4) with weight coefficients k<sub>i</sub>, which are appointed by experts depending on particular indicators or the availability of observations of cracks and sediments of the foundations. The criterion for solving the problem of reducing the hazard of an emergency situation, through preventive and protective measures, is to reduce the values of the complex R-indicator to close to zero. The solution of this problem is very important for cities, as built-up area is characterized by heterogeneity and variability, both in time and in space. Such territory should be operated in accordance with the basic principle of geological reliability and safety with real and potential flooding.
