The forces between the slices are neglected and each slice is considered to be an independent column of soil of unit thickness. The Fellenius (or Swedish ) Solution. It is assumed that for each slice the resultant of the interslice forces is zero.

Also, no limit was imposed on the shaft resistance calculation for the Takesue method since the … D-Geo Stability is a slope stability package for soft soils. Previous releases of D-Geo Stability were named MStab. Deltares systems tools follow best practice, and are developed according to modern software standards; therefore they are user-friendly and easy to learn. However, instead of doing that, they placed great emphasis on the factor of safety of 1.14 that they obtained using the Fellenius Method with total unit weights, which was only 57 percent of their “most correct” solution. The details of their programming are unknown and we have not been able to reproduce that number, but that is not critical. In the method of slices, also called OMS or the Fellenius method, the sliding mass above the failure surface is divided into a number of slices. The forces acting on each slice are obtained by considering the mechanical (force and moment) equilibrium for the slices.

N' = Wcosa — ul. Hence the factor of safety in terms of effective stress(Equation 3) is given by: The geotechnical engineer frequently uses limit equilibrium methods of analysis when studying slope stability problems, for example, Ordinary or Fellenius’ method (sometimes referred to as the Swedish circle method or the conventional method), Simplified Bishop method, Spencer’s method, Janbu’s simplified method, Janbu’s rigorous method, Morgenstern-Price method, or unified solution scheme [1–3]. In order to reduce the influence of the assumptions made in limit equilibrium methods In the current practice, to determine the safety factor of a slope with two-dimensional circular potential failure surface, one of the searching methods for the critical slip surface is Genetic Algorithm (GA), while the method to calculate the slope safety factor is Fellenius slicesmethod.HoweverGAneedstobevalidatedwithmorenumerictests,whileFellenius slicesmethodisjustanapprox- imatemethodlike niteelementmethod. ispaperproposedanewmethodtodeterminetheminimumslopesafetyfactorwhich Based on the method of infinite article points to the theoretical basis of the loess slope stability analysis is even the Fellenius article point method.

Stability Analysis of Finite Slopes Using the Swedish Circle Method: The simplest and most basic limit equilibrium method is known as the Fellenius Method of Slices.The Fellenius Method assumes that the moment arm is the same for both the driving and resisting forces, i.e, that these forces are collinear. This method was developed by the Swedish geotechnical pioneer Wolmar Fellenius (1876-1957). Swedish circle method for analyzing the slope stability: This method was first introduced by Fellenius (1926) for analysis of slope stability of C-φ soil. In this method, the soil mass above the assumed slip circle is divided into a number of vertical slices of equal width. The forces between the slices are neglected and each slice is considered to be an independent column of soil of unit thickness.

The simplest basic method is known as the Normal or Ordinary Method of Slices, also known as Fellenius’ method or the Swedish circle method of analysis. methods of slope stability using limit equilibrium, finite element, and other methods are frequently reported (Duncan and Wright 2005).
