ABSTRACT

A localized probabilistic approach for slope stability analysis is presented in this paper, which is also applicable for the risk assessment of slope failure at a specified confidence level. The probabilistic analysis as well as its localization was achieved through the probabilistic characterization of the in-situ strength values, that provide the full statistical distribution of strength variables at every point within the geological formation. An actual case study was made for a surface coal mine to demonstrate its superiority and to show its technical details.
