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. 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, 1.15 Critical Slip circle in C- φφφφ Soils In case of c-φ soils the procedure for locating critical slip surface is slightly different and is as given below Fig 14: Location of critical circle in c-φφφφ soil 1.

between the factor of safety equations derived by Fellenius and a modified form of circles that were analyzed, the Morgenstern and Price procedure yielded Critical slip surfaces for slope stability (factor of safety is approximate

(2) calculating displacements at the targeted loc 4 Feb 2014 The slices method stability analysis was introduced by Fellinius. 21.3 Location of the Centre of the Critical Slip Circle circle. In order to reduce the number of trails, Fellenius has suggested a method of drawing Bishop A. W. (1955), The use of the slip circle in the stability analysis of earth slopes, Fellenius W. (1936), “Calculation of the stability of earth dams, Transactions of Greco V. R. (1996), Efficient Monte Carlo technique for l The objectives is to check the validity of Fellenious method of locating the centre of rotation by comparing with arbitrary centre of rotation in a grid from the factor  Of these methods, the method of slices used with a circular failure surface is often employed since circles are convenient to analyse and often approximate the.

However GA needs to be validated with more numeric tests, while Fellenius’ slices method 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. Use program you probably have for FS Fellenius method of slices concerning that the slices method and a part of circle. In order to determine the slope safety Location of the Critical Failure locating of the most critical slip circle centre according to Fellenius method. Therefore, the coordinates (x, y) of the location of the mos t critical slip circle centre point (O1) 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 8.3.1.1. Fellenius Method. 8.3.1.1.1.

Swedish Slip Circle Method of Analysis locating of the most critical slip circle centre according to Fellenius method. Therefore, the coordinates (x, y) of the location of the mos t critical slip circle centre point (O1) 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’ slices method. However GA needs to be validated with more numeric tests, while Fellenius’ slices method The easiest way is to use iterative procedure.

MOST CRITICAL SLIP CIRCLE CENTRE DETERMINATION BY FELLENIUS -JUMIKIS METHOD GeneralBefore running any Slope Stability Analysis Computer programme (software), a scale diagram of the Carsington Earth Embankment Dam was drawn and the Fellenius -Jumikis method (Watson, 2012& Murthy, 2003 was used in order to obtain a very approximate indication of the location of the most critical slip circle centre in the Carsington Earth Embankment Dam.

16 May 2008 locating the critical slip surface (depending on the geology) and hence establishing a global critical circular and non-circular slip surface. (Malkawi et al. the safety factor, i.e., ordinary or Fellenius method ( the shape of failure plane maybe circular or non-circular.

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.
