Two methods known as modified Fellenius’s method and modified Bishop’s method are used in this study. The Fellenius (Swedish) Method Fellenius assumed that the resultant of the inter-slice forces is zero, then N’ = W cos α–ul Hence the factor of safety in terms of effective stress is given by: The components W cosαand W sinαcan be determined graphically while angle a can be calculated or measured 2.1.Fellenius Method In this section, we will introduce Fellenius method as a method of the study. As mentioned earlier that this method divided the potential sliding mass into sub vertical slice (see Figure 1). It is meant to obtain and to calculate the factor of safety (F) each slice easily.

Fellenius method

FELLENIUS METHOD: This is a modified version of the Method of Slices. (Anderson dan Richard, 1987) Prinsip Dasar Metode FelleniusMetode Fellenius (Ordinary Method of Slice) diperkenalkan pertama oleh Fellenius (1927,1936) berdasarkan bahwa gaya memiliki sudut kemiringan paralel dengan dasar irisan FK dihitung dengan keseimbangan momen. Bengt H. Fellenius. The installation of piles by vibratory methods is discussed and illustrated by case histories.

The approach is applied to a case study involving 100 ft to 190 ft long piles and is also a demonstration of the use of UniPile in an engineering project.

discussing the usual method or Fellenius method, Bishop In the method of calculation of the safety factor of the slope stability, a methodfrequently used in calculating the slope stability is by Fellenius method ( Ordinary There are several available methods that can be used to perform a circular arc also known as Fellenius' method or the Swedish circle method of analysis. The paper reports the measurements and analyses and indicates the method for determining the residual load, the strain - dependent modulus of the test piles The simplified Bishop method uses the method of slices to discretize the soil mass and determine the FS (Factor of Safety). This method satisfies vertical force Abstract. In this research, a new three-dimensional limit equilibrium method was developed.

The solution involves resolving the forces on each slice normal to the base, i.e. 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 Methods (General): There are several available methods that can be used to perform a circular arc stability analysis for an approach embankment over soft ground. 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.
