Abstract: in the limit equilibrium method of rotational stability analysis of reinforced embankments on sof't soils, the maximum required reinforced force is determined assuming that the eitforced acts in a particular direction The reinforcement force is commanly assumed to act in the horizontal direction ( X = O) as this gives a conservative estimate of the required reinforcement force. The other two directions which have been recommended/or use are: tangential to the failier surface at the point where the failure surface intersects the reinforcement force ( x = 0), and in the direction of the bisector to the horizontal and tangential directions ( x = 0/2). The assumed direction of reinforcement force has an influence on its magnitude and therefore ¢n the selection of reinforcement to he used in the emhankment. This paper presents the results of studies carried out to investigate the influence of the direction of the reinforcement force on its magnitude. First, solutions are presented for the location of the critical failure surface and the maximam required rainforcement force for two additional directions, namely, x = 0/4 and x = 30/4. Using these and also the other available solutions for different direc-tions. two example embankments have been analysed. The results of the analyses are presented in the second part of the papre. Tentative guidelines for the selections of x are also suggested.
