Abstract: Solutions for the rotational stability analysis of unreinforced and reinforced embankments on soft soils have been developed. The general case of an embankment having a partial-height dry tension crack, a berm, and an excavation outside the berm has been considered. A limit equilibrium method assuming a circular slip surface and total stress analysis have been used. In reinforced embankments, three different directions of reinforcement force have also been considered. The solutions are presented in the form of simple equations. Using these equations, the location of the critical slip circle, and the minimum factor of safety can be calculated directly for unreinforced embankments, for a given limiting tangent. Similarly, for reinforced embankments, the equations can be used to calculate the location of the critical slip circle and the maximum required reinforcement force, for a given limiting tangent. The conditions that are to be satisfied to get valid solutions are described. The use of the solutions is explained with illustrative examples.
