[4] The Ordinary Method (Figure 1b) [Fellenius, 1936] is the simplest and the oldest method of slices. It ignores all the inter The slope stability analysis is crucial in engineering practice to ensure the stability of structures and prevent loss of human life and money. The common methods for the analysis of a slope’s stability are Culmann Method, Ordinary Method of Slices and Bishop Method of Slices.

Sarma method – The method of Sarma is a simple, but accurate method for the analysis of slope stability, which allows to determine the horizontal seismic acceleration required so that the mass of soil, delimited by the sliding surface and by the topographic profile, reaches the limit equilibrium state (critical acceleration Kc) and, at the same time, allows to obtain the usual safety factor possible; otherwise much flatter slopes will be needed. When using the infinite slope method, if the FS is near or below 1.0 to 1.15, severe erosion or shallow slumping .

The coefficients m and n are functions of the dimensionless number c'/gH and the depth factor D. Example. Using the Fellenius method of slices, determine the factor of safety, in terms . of effective stress, of the slope shown in Fig.(6) for the given failure surface. The groundwater analysis is run first, followed by the slope stability analysis.

of effective stress, of the slope shown in Fig.(6) for the given failure surface. 2020-03-24 This method has been widely and successfully used in practice for the evaluation of the short term stability of saturated clay slopes. For example, Ireland (1954) has demonstrated the validity of this technique in the analysis of the short term stability of a slope excavated in saturated soil.
