Abstract
In recent years the evaluation of failure probability on slope stability analyses has become important because it has been presented as a representative method helping to complement the factor of safety. As part of this paper, it is proposed the evaluation of the failure probability in cut slopes on residual soils from the Aburrá valley. Statistical analyses were performed on the most important variables, considering continuous statistical distributions. Sensitivity analyses were performed to quantify their influence in the stability. As a result, some abacuses are developed in which the height and the slope angle are related to the failure probability and the factor of safety, proposed from the mean values of the chosen variables. To evaluate the failure probability, the Taylor series technique and the First Order Second Moment methodology were used. The obtained results allow the estimation of the probability that a slope of certain features may fail.
