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 (ru) which identify the position of the critical slip circle. A set of stability charts is also given. On decrit une methode d'analyse pour determiner le facteur de securite d'un remblai contre la rupture sur une surface de glissement cylindrique. L'analyse est faite d'apres la contrainte effective ett amene a deux equations d'equilibre, la premiere se rapportant aux forces et la deuxieme aux moments. En utilisant cette method d'analyse, on a etudie les facteurs qui affectent la precision de la methode sim...
