Synopsis A method of analysis is described for determining the factor of safety of an embankment against failure on a cylindrical slip surface. The analysis is in terms of effectivce stress and leads to two equa-tions of equilibrium, the first in respect of forces and the second in respect of moments. Using this method of analysis, the factors affecting the accuracy of Bishop's simplified method have been investigated. Charts have been obtained for three different values of the pore pressure coefficient (r u ) which identify the position of the critical slip circle. A set of stability charts is also given. On décrit une méthode d'analyse pour déterminer le facteur de sécurité d'un remblai contre la rupture sur une surface de glissement cylindrique. L'analyse est faite d'après la contrainte effective ett amène à deux équations d'équilibre, la première se rapportant aux forces et la deuxième aux moments. En utilisant cette méthod d'analyse, on a étudié les facteurs qui affectent la précision de la méthode simplifiée de Bishop. On est arrivé à des diagram-mes pour les trois valeurs différentes de coefficient de pression interstitielle (r u ) quiidentifient la position du cercle de glissement critique. On donne aussi un groupe de diagrammes de stabilité.

... Even though those approaches stand out as a result of their ability to represent complex behavior of soils, they are computationally expensive and time consuming. Alternatively, Limit Equilibrium Methods (LEM) based on the quantification of the driving and resisting forces along a failure surface are used for SF assessment (Bishop 1955a;Janbu, Bjerrum, and Kjaernsli 1956;Morgenstern and Price 1965a;Spencer 1967;Qian et al. 2019a). In comparison with numerical models, LEM can quickly compute the SF considering a set of hypotheses (Duncan and Wright 2005;Huang 2014). ...
