Janbu’s (1957) simplified use of Janbu, Fellenius, and Bishop methods applied horizontal forces when using Janbu method insertion of circles by identifying three points or a center and radius zone reinforced with geogrids and other materials submersed slopes graphic and numeric insertion of polygonal surfaces automatic calculation and identification of the critical surface The main objectives of slope stability analysis are evaluating factor of safety for a given slip surface and determining the critical slip surface for a given slope. Factor of safety is usually calculated by limit equilibrium method. The main steps to determine the critical slip surface are generating trial slip surfaces as probable solutions and searching among them to determine the one with The centre of most critical circle is located using Fellenius method. Adopting limit equilibrium method, under the influence of weight of potential sliding mass and seismic inertia forces, factor of safety is evaluated applying new pseudo-dynamic method based on visco-elastic behaviour of soil which satisfies zero-stress boundary condition and considers soil amplification inherent to soil Ordinary Method of Slices (Fellenius, 1927) Moment equilibrium about center of circle .

The initial method adopted for undertaking LE analysis was the Fellenius or Swedish circle method (Fellenius, 1936). 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. Bishop (1955) developed a revised method for undertaking the sliced method yulvi zaika 8. sliced method • this method can be used for soil in different shearing resistance along the failure plane • proposed by fellenius ,bishop, janbu, etc • assumed circular failure plane 9. regulation of slices 1. sliced performed vertical direction 2.

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. [3] Fellenius, W., Calculation of the stability of earth dams. 16 May 2008 locating the critical slip surface (depending on the geology) and hence establishing a global critical circular and non-circular slip surface.

in/ and get access to our study package comprising of video  Fig 1 Fellenius method for locating centre of critical slip circle. The forces acting on the wedge slices have been calculated by the following parameters: i = slope   The method of slices was introduced by Fellenius (1936) where he divided the Using SLOPE/W, hundreds of runs were made to locate the critical circles of  problems include the Fellenius Method (also called Ordinary Method o f Slices or that used an automatic search scheme to locate the critical slip surface on the basis portion of the critical circle was also found to be relatively Bishop Method (1955), simplified Janbu method (1954), and Fellenius method ( 1927).

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.

3D-EFFECTS IN TOTAL STABILITY EVALUATIONS - Geoteknik

The system probability of failure considering all potential slip circles is compared with the correspond-ing probability of failure with respect to the "fixed" critical deterministic slip circle. The differences in the results calculated by the three MCS methods were investi-gated. Two computer programs (SWASE and REAME) developed for the analysis of plane and cylindrical failures respectively, are fully explained.

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. 2014-12-01 · Generally, modified Fellenius׳ and simplified Bishop׳s methods based on slip circle of slices have been used for slope stability analyses and calculation of bearing capacity in geotechnical practices over the years and those are found to be popular among the designers and researches elsewhere though there are number of sophisticated methods available in the literature. The initial method adopted for undertaking LE analysis was the Fellenius or Swedish circle method (Fellenius, 1936).
