This method can only be applied to circular slip surfaces and leads to significant underestimation of the factor of safety (FoS) and is now rarely used. 2001-02-13 Analysis of slope stability is very important as many structures in hilly areas failed due to instability of slope. The aim of this study is to determine the factor of safety (FOS) of slopes located at Pahang Matriculation College by using limit equilibrium method. 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.

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. In the Fellenius method [2], the inter-slice forces were neglected 18 Apr 2015 DeBeer double-log intersection. Fuller-Hoy Curve Slope. The Creep Method.

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. The basics of the Fellenius Unified Pile Design of Capacity, Negative Skin Friction (Dragload and Downdrag), and Settlement. 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. 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 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).
