... is to evaluate the effect of joint spacing in the estimation of the factor of safety of rock slopes affected by potential wedge failures. For this purpose, a 3D numerical distinct-element code (3DEC) was selected to carry out a good number of simulations in which the factor of safety a slope, affected...

..., in particular determination of factor of safety and location of the critical circular failure surface, are useful during the preliminary stages of open pit design. Among others, such tools allow the engineer to gain insight in the role that the different variables controlling the problem have in defining...

... of slopes on the basis of rock mechanics is required. This paper outlines a back analysis method originally proposed by Sakurai in 1987 to estimate the factor of safety from the measured displacements. Two case studies are demonstrated to confirm the validity of the method. By applying the back analysis...

... Abstract Many of the concrete dams in the western world today have reached a considerable age. With an ageing population of dams, re-assessment of their structural safety is becoming increasingly important to ensure that failure does not occur because of material deterioration in the dam body...

The limit states slope stability using the reduced uniaxial compressive strength does not provide the same factor of safety when the reduced equivalent Mohr-Coulomb (MC) parameters are utilized in the analysis. This study aims at developing...

From some studies and investigations carried out in the last years (Rico et., 2008, USEPA, 1994) including the most relevant tailings dam failures that took place in the last decades, the most common...

... Abstract A probabilistic analysis is applied to rock slope stability with an example case of a rock slope with translational potential failure mode. The capacity and the demand are represented as independent triangular random variables. The distribution of the factor of safety is found...

... of saturation conditions on the safety factor of the slope using Rocscience Inc. software. Introduction In open pit mining, the design of the rock slopes has to remain stable for the period of excavation as well as for the life span of the mine. There are many factors that have to be considered in slope...

The factor of safety, defined as the ratio of the capacity of the rock to the pertinent demand, allows for the estimate of the structural reliability of mining operations. However, this factor does not account for the variability of the parameters involved...
