Abstract
This work further develops the method for assessing reliability of gate chambers by the criteria of stability loss against displacement and overturning, as well as floating up. The work considers the random nature of the external loads and impacts, which the gate chambers bear during operation, as well as correlations between them. It also considers the random nature of mechanical properties of the foundation soils and correlations between them. For solving this problem, the method of statistical tests (Monte Carlo method) was applied, which is widely used for assessing probabilistic reliability of complex technical systems. A numerical probabilistic assessment of the risk when the gate chambers on rock foundation at hydro schemes of the Dnieper Cascade reach the boundary conditions has been performed. In the future, the proposed method could be used in probabilistic reliability analyses of hydraulic structures and cascades of hydro schemes, taking into account the correlations between natural factors: hydrological characteristics, ice, and wind, as well as temperature loads and impacts.
