===General acceptance===

The Sarma method has been extensively used in seismic analysis software for many years and has been the standard practice until recently for seismic slope stability for many years (similar to the [[Mononobe–Okabe method]] <ref>Okabe, S. (1926) General theory of earth pressures. Journal of the Japanese Society of Civil Engineers, 12 (1)</ref><ref>Mononobe, N & Matsuo, H. (1929) On the determination of earth pressures during earthquakes. Proceedings of the World Engineering Congress, 9.</ref> for retaining walls). Its accuracy has been verified by various researchers and it has been proved to yield results quite similar to the modern ''safe'' [[Lower Bound]] numerical stability [[Plasticity (physics)|Limit Analysis]] methods (e.g. the 51st [[Rankine Lecture]] <ref>{{Cite journal | last1 = Sloan | first1 = S.
