Abstract
Slope stability analyzes correspond to the evaluation of the safety factors commonly performed through the limit equilibrium and finite element methods. Due to the uncertainty of the geotechnical parameters, different statistical methods have emerged such as the limit equilibrium combined with the Monte Carlo simulation method and the random finite elements, which have been widely accepted in recent years. Normally, these analyzes are not performed taking into account the geological influence on the geotechnical properties, so in this work we proceed with the comparison of several geometrical typologies of slopes for mudflows and a residual soils of the Stock San Diego. These geologies according to the standard penetration test presents similar geo-mechanical characteristics in addition to similar grain size distribution, but their statistical parameters obtained by several laboratory tests shows a noticeable difference between them. The results show that the long-term safety factors of the mudflows are more susceptible to geometric changes with respect to the residual soils. The residual soils present a better conditions of stability in the short term analysis. The statistical parameters obtain higher safety factors in the residual soils. The probabilities of failure by random finite elements are substantially greater on the residuals and, finally, that the greater deformations occur in the mudflows under 1:1 slopes and 1: 0 in the residual soils.
