CAMACHO-OROZCO, Sebastián  e  RAMOS-CANON, Alfonso Mariano. Failure potential index for slopes conditioned by landforms. Bol. cienc. tierra [online]. 2016, n.40, pp.39-45. ISSN 0120-3630.  https://doi.org/10.15446/rbct.n40.53658.

The paper contributes to the understanding of the effect of three-dimensional landforms in the slope stability through to the analysis of nine models, which result from the combination of three different landforms in plant and profile view (straight, convex and concave). The analysis is based on the calculation of a failure potential indexwhich represent a unified way a stability value for each model. The procedure was performed by mean of finite element numerical simulations with a Mohr-Coulomb elastoplastic model applied to each geometry in homogeneous solis. We take into account permanent flow and partial saturation above of the flow surface within the slope. Finally, it is quantified the failure susceptibility of the nine models by mean of the assignation of a failure potential index. With this assignation, it is possible to stablish an order of priority of the susceptibility of the slopes in function of geomorphology of each model.
