Rewriting Equation (1): This method of slope stability analysis is not widely used since it has been found that plane surfaces of sliding are observed only with very steep slopes, and for relatively flat slopes the surfaces of sliding are almost always curved. EXAMPLE Referring to Fig. 4.2 H = 16m tan i = 2/3 tan θ = 1/3 c = 10kPa φ = 35˚ methods known as modified Fellenius’s method and modified Bishop’s method are used in this study.

2014-12-01 · The slip circle method of slices is commonly used in the analyses of slope stability and bearing capacity for multi-layered ground. However, in the case of ground consisting of horizontal sandy layer, it is known that modified Fellenius׳ method tends to underestimate the factor of safety, while simplified Bishop׳s method tends to overestimate the factor of safety. Wolmar Knut Axel Fellenius (né le 10 septembre 1876 [1] à Viksberg ; † 2 septembre [2] 1957 à Stockholm) est un géotechnicien suédois.Il a laissé son nom à une méthode statique d'analyse de la stabilité des pentes, toujours utilisée en mécanique des sols. method. b.

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.

The method was developed by Fellenius, he assumed that the potential sliding mass has been divided into sub vertical slice and each slice had own weight (W) [9, 10]. Based on the explanation above, the authors would investigate variational effect of slope geometry using Fellenius Method. 1.
