Abstract: Mononobe‐Okabe (M‐O) method is still employed as the first option to estimate lateral earth pressures during earthquakes by geotechnical engineers. Considering some simple assumptions and using a closed form method, M‐O solves the equations of equilibrium and suggests seismic active and passive lateral earth pressures. Therefore, the results are true in its assumption range only, and in many other practical cases, M‐O method is not applicable. Noncontinues backfill slopes, cohesive soils, and rising water behind the wall are some well‐known examples in which the M‐O theory is irrelevant. Using the fundamental framework of M‐O method, this study proposes an iterative method to overcome the limits of the M‐O method. Based on trial and error process, the proposed method is able to cover many of the defects which regularly occur in civil engineering when M‐O has no direct answer.
