• Berms are often used to improve the stability of embankments. The analysis for rotational stability is usually carried out by using limit equilibrium approach assuming a circular slip surface. Since the embankments on soft soils are not very high and are constructed quickly, a total stress analysis is carried out to evaluate the factor of safety at the end of construction. Most of the available methods require a trial and error procedure to determine the minimum factor of safety. Solutions are presented in the paper in the form of simple equations using which the location of the critical slip circle aud the minimum factor of safety can be calculated directly for a given limiting tangent. In the first part of the paper, the slip circle has been assumed to pass through the foundation soil and the embankment. Due to the rigidity of the embankment, tension cracks may develop in the embankment. The second part of the paper considers the presence of full height dry tension crack in the embankment. The solutions make possible a quantitative evaluation of the effect of berms and of tension crack on the stability of embankments. The optimum dimensions of the berms also can be chosen.
