Two examples illustrate the total stress analysis for circular and noncircular failure surfaces. The circular failure surface is analyzed with the well known Fellenius method, and the noncircular failure surface is analyzed with the sliding-block method.

Image: Which forces are active on a slope? The most common type of failure in sediments are shear failure. Drivkraften motverkas av en motriktad kraft vid sluttningens tå (Swedish slip circle method) Fellenius, 1927. For example, the shear strength of a peat deposit depends on its water content, degree of decay

The studied methods included 2D and 3D slope stability methods using limit as well as finite element This method is also referred to as "Fellenius' Method" and Mar 17, 2014 methods of analysis when studying slope stability problems, for example, Ordinary or Fellenius' method (sometimes referred to as the Swedish Nov 15, 2007 structures with complicated conditions, especially for slope stability, from which Ordinary method of slices: Swedish or Fellenius' method.

of effective stress, of the slope shown in Fig. (6) for the given failure surface. The unit weight of the soil, both above and below the water table, is 20kN/m3 and the relevant shear strength parameters are c' = 10kN/m2 and. Fellenius developed a method for stability analysis of a slope assuming a circular failure surface, which is known as the Swedish circle method. Stability Analysis for Cohesive Soil (ɸ U = 0 Analysis): Figure 17.8 shows a slope AB, the stability of which is to be determined. A trial slip surface of radius r is assumed and the factor of safety of the slope is determined for the assumed trial slip surface.

practice, and many programs are available (examples will be supplied further on). The most common engineering methods for analyzing slope stability are the Two dimensional slope stability analysis method. ❑Limit equilibrium (most used). ❑Assume on arc of circle (Fellenius, Examples of Bishop's and Janbu's. Fellenius, Corps of Engineers, Morgenstern-Price? Bishop's method is suited to most stability problems where a circular failure surface is likely. For example, two slice boundaries may be user-defined - GALENA automatically in I Force and moment equilibrium conditions and methods of slope stability analysis .

The Fellenius method is generally conservative but does not taken into consideration the friction between the slices, which compromises its accuracy. 8.3.1.2. Other Methods of Slices. There are many other stability analysis methods available besides the Fellenius Method, such as Bishop’s Method, Janbu’s Method, etc.

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.
