Reliability

Engineering always deals with uncertainties, and efforts are needed to quantify them. A probabilistic analysis considers the statistical information of the problem to this quantification. In the geotechnical area, uncertainties play a particular role in structure design because it deals with naturally formed materials. Evaluating spatial variability has...

Probabilistic and deterministic stability analyses of the progress of a large mine pit excavation in Brazil are presented herein. A simple method of reliability analysis for quantifying the probability of failure of slopes has been considered and its advantages and limitations are briefly discussed. The variance of the factor of safety is computed for s...
