In the simplest method of slices (known as Fellenius' method or Swedish method of slices), the resultant of all inter-slice forces is assumed to be consistent with the direction of failure arc for the slice. With this assumption, there are no resultant forces acting on … The Fellenius (or Swedish ) Solution. It is assumed that for each slice the resultant of the interslice forces is zero. The solution involves resolving the forces on each slice normal to the base i.e.
The soil at Pahang Matriculation College can be classified as sandy SILT with high plasticity. • Task 1 (Week 11) – Fellenius method (Method of slices) to calculate FOS: Assume homogeneous soil layer with a single set of soil parameters by considering weighted average method … (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. Authors: Abdulrahman Abdulrahman, Abir Abdulrahman Abstract: The stability of slopes of earthen embankments is usually examined by Swedish slip circle method or the slices method. The factor of safety against sliding using Fellenius procedure depends upon the angle formed by the arc of sliding at the center ψ and the radius of the slip circle r.

– – N. i = W. i. cos( i) – U From the analysis, the result indicate that the factor of safety (FOS) value of Bishop's Simplified method (1955) was 7.65 % higher than Fellenius's method for 0 kPa suction, which mean that the 1. Stability Analysis of Finite Slopes – Culmann’s Method: Culmann (1866) considered a plane failure surface and the 2. 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.
From the calculation by Fellenius method, the safety factor of slope 1:1.5 is between 1.474 to 1.508, while the safety factor of slope 1:1 is between 1.334 to 1.487.On the slope stability analysis with Plaxis software, each type of slope is reviewed in three assumptions soil behavior type, the type are drained, undrained, and nonporous.

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. Fellenius method 2.
