Assessment practice of geomechanical risks for slopes and retaining walls

Abstract

The methods of geomechanical analysis are considered, which together allow to correct and propose new proactive approaches to ensure the geomechanical safety of slopes and retaining walls of mining structures. A very promising solution to this problem is the addition of a traditional deterministic measure for assessing the condition of slopes and retaining walls, i.e. safety margin factors, with simulation quantitative assessments of risk levels that objectively reflect the instability of the environment. In such a complex, the deterministic block performs insurance functions and determines that the results of the analysis do not contradict the requirements of regulatory documents; simulation (according to the Monte Carlo method) provides an unambiguous solution on the factors of economic and social security, eliminates or significantly reduces the likelihood of making unnecessary costs.
