Only planar rupture surfaces have been considered and hence wall friction angle has been restricted upto one-third the soil friction angle. This approach results in the same seismic passive earth pressure coefficients as that obtained by Mononobe-Okabe approach, besides giving additional information about the distribution of earth pressures. The paper presents the results for various wall batter angles, soil friction angles, wall friction angles and the horizontal and vertical seismic acceleration coefficients. It has been found that in the seismic case, passive resistance acts at a rd point other than at 1/3 from the base of the wall. Under seismic conditions, the extension of failure zone is more than that under static conditions.
