An analytical method is presented for analysis of slope stability involving cohesive and non‐cohesive soils. Earthquake effects are considered in an approximate manner in terms of seismic coefficient‐dependent forces. Two kinds of failure surfaces are considered in this study: a planar failure surface, and a circular failure surface. The proposed method can be viewed as an extension of the method of slices, but it provides a more accurate treatment of the forces because they are represented in an integral form. The factor of safety is obtained by using the minimization technique rather than by a trial and error approach used commonly. The factors of safety obtained by the analytical method are found to be in good agreement with those determined by the local minimum factor‐of‐safety, Bishop's, and the method of slices. The proposed method is straightforward, easy to use, and less time‐consuming in locating the most critical slip surface and calculating the minimum factor of safety for a given slope.
