The easiest way is to use iterative procedure. In first loop, you vary XY coordinates of the centre and then you use second loop to vary radius of slip circle.

Overview. 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. 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. 1. Introduction. 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 The slip circle method of slices is commonly used in the analyses of slope stability and bearing capacity for multi-layered ground.

Canadian Geotechnical Journal, 38(5): 1081–1089. 31 Oct 2003 Various methods can used to locate the most critical circular The Ordinary Method of Slices (OMS) was developed by Fellenius (1936) and is. Locating the critical failure surface of a soil slope is rendered erroneous and large to employ the trial and error method in a computationally efficient fashion.

In this solution, safety factor is determined with Fellenius' method of slices as in . Fellenius' method of searching for the critical failure surface was given as follows. If soil internal friction angle = 0, 2D critical failure surface passes through slope toe A and can be determined by Figure 5 and Table 13.

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. In this solution, safety factor is determined with Fellenius' method of slices as in .

Location of Most Critical Circle in the Carsington Earth Embankment DamBy applying the above mention procedure, according to Fellenius -Jumikis method, the following on scale diagram of the Carsington Earth Embankment Dam cross section was drawn ( Figure 8) and a very approximate indication of the location of the most critical slip circle

The slip circle with a minimum FS is called critical slip circle. 21. 1.13 Critical Slip Circle by Fellenius Direction angles In case of slopes in homogeneous cohesive soil deposits, the centre of a critical circle can be directly located by using Fellenius direction angles. Se hela listan på hindawi.com 2 In limit equilibrium method it must search for critical surface by using geometry. In finite element method the critical surface is automatically find out by various software’s. 3 The advantages of limit equilibrium method: The limit equilibrium method of slices is based on purely on the principles of statics; that is, the For reducing the number of trials, Fellenius has suggested the method for drawing a line (PQ) on which the locus of critical circle is fixed. The procedure to locate the line PQ for the downstream and upstream slopes of the embankment is shown in Fig. 18.14 (a) and 18.14 (b), respectively.
