Abstract: In the rotational stability analysis of reinforced embankments on soft ground, the maximum required reinforcement force to achieve the desired target factor of safety is usually determined by a total stress analysis, using a limit equilibrium approach and assuming a circular failure surface. Solutions are presented in the paper for the case when the reinforcement force is assumed to act in the direction of the bisector to the horizontal and tangential directions at the point where the failure surface intersects the reinforcement. In the first part of the paper, the failure surface is assumed to pass through the foundation soil and the embankment. The second part of the paper considers the presence of a full height dry tension crack in the embankment. The presence of a berm is considered. Solutions for the location of the critical failure surface and the maximum required reinforcement force are presented in the form of simple equations. A few example problems are solved by using the solutions presented in the paper. The results agree well with the values obtained using other solutions.
