Évaluation complémentaire d'une méthode simple, générale et rigoureuse d'évaluation de la stabilité des pentes

<div> In this paper, a further assessment of the simple, general and rigorous slope stability method developed by Alexandre and Thomasi (2025) [1] is reported. The method makes no assumption related to inter-slice forces, does not enforce a constant safety factor along the potential slip surface and is not tied to any specific failure criterion. In order to match the number of unknowns and equations of this notoriously statically redundant problem and still retaining simplicity, a small modification is introduced in the geometry of vertical slices. Studied cases include circular and non-circular slip surfaces, homogeneous and non-homogeneous soil profiles, Mohr-Coulomb and Power Law failure criterion as well as cases related to the assessment of probability of failure, progressive failure and surfaces containing tension cracks. Comparisons between previously published stability analysis and the new method show results that are either on par or are slightly conservative in relation with established methods such as Spencer (1967) [2], Sarma (1973) [3] and Morgenstern-Price [4]. It is also shown that, in spite of its simplicity, the new method offers some advantages over classic Limit Equilibrium methods. </div>
