Figure 4 shows the detail of slope geometry with slip surface and location of slices by Ishak (2014). Ishak (2014) used this detail geometry in his research to calculate slope stabilization using Fellenius’s method (1936) equation for unsaturated soil which had been modified by Rees and Ali (2012).

av C Ghirardini · 2016 — In chapter 4 there is the description of the slope stability analysis with the two methods of Bishop and Fellenius, and the resulting slope stability 

For slopes in unsaturated conditions (20 kPa suctions), the FOS are between 1.550-3.702 when Swedish Circle Method. Swedish circle method for analyzing the slope stability: This method was first introduced by Fellenius (1926) for analysis of slope stability of C-φ soil. In this method, the soil mass above the assumed slip circle is divided into a number of vertical slices of equal width. possible; otherwise much flatter slopes will be needed. When using the infinite slope method, if the FS is near or below 1.0 to 1.15, severe erosion or shallow slumping . Slope Stability Analysis Geotechnical Design Manual M 46-03 Chapter 7-4 December 2006 Slope Stability Analysis Slope Failure is the movement of mass on slope (falls, slides, flows) Landslide: involves an extensive area, mild slope (<20o), movement is slow and gradual.

Morgenstren and Price Method is used for analyzing the slope stability in moment eq uilibrium for general slip slope … 2. Stability Analysis of Finite Slopes Using the Swedish Circle Method: Investigations carried out in Sweden on slope failures indicated that the failure surface resembles the arc of a circle. Fellenius developed a method for stability analysis of a slope assuming a circular failure surface, which is known as the Swedish circle method. The study evaluated four methods for calculating slope stability. Fellenius (FELLENIUS, 1936), Bishop (BISHOP, 1955), Simplified Bishop (BISHOP & MORGENSTERN, 1960) and Simplified Janbu (JANBU, 1973) were compared with the Spencer method (SPENCER, 1967), which is considered an accurate method for calculating the factor of safety (F S). Fellenius and Taylor method for slopes in homogeneous clay soil with 휙 = 0 Stability problems of this type have been solved analytically by Fellenius (1927) and Taylor (1937). For the case of critical circles, the developed cohesion can be expressed by the relationship Note that the term critical circles, the developed cohesion can be expressed by 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, About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Analysis of slope stability is very important as many structures in hilly areas failed due to instability of slope.

FHWA NHI-06-088 6 – Slope Stability Soils and Foundations – Volume I 6 - 3 December 2006 6.1 EFFECTS OF WATER ON SLOPE STABILITY Very soft, saturated foundation soils or ground water generally play a prominent role in geotechnical failures in general. They are certainly major factors in cut slope stability and in

If SF< 1.5 to stage V. Methodology of Slope Stability Analysis It is a method to expresses the relationship between resisting forces and driving forces •Driving forces –forces which move earth materials downslope. Visual Slope-Slope Stability Analysis module was developed based on commonly excepted limit plastic equilibrium theory, method of slices and finite element method that have been described in many text books.

In the mid-1950s Janbu (1954) and Bishop (1955) developed advances in the method. Figure 4 shows the detail of slope geometry with slip surface and location of slices by Ishak (2014). Ishak (2014) used this detail geometry in his research to calculate slope stabilization using Fellenius’s method (1936) equation for unsaturated soil which had been modified by Rees and Ali (2012).

been used to analyse slopes. This approach makes use of a number of differing analysis methods depending on the type of problem (circular vs non-circular) to be solved and the required accuracy of the result. The initial method adopted for undertaking LE analysis was the Fellenius or Swedish circle method (Fellenius, 1936).

Finally, two numerical examples, including a homogeneous slope and a two-layered slope, are used to verify the proposed methodology with the Fellenius method . 2. values obtained from each method are almost equal with the difference value is around ± 0.1 as shown in Table 2. 3.
