The verification methodology of the Several limit equilibrium methods have been developed for slope stability analysis. Fellenius (1936) introduced the first method which is referred to as the Ordinary Rapid Drawdown Analysis Methods .

of effective stress, of the slope shown in Fig.(6) for the given failure surface. 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). Figure 4 shows the detail of slope geometry with slip surface and location of slices by Ishak (2014).

Fellenius method for slope stability pdf

IntroductionSince the 1930s, the limit equilibrium (LE) approach has 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).

The verification methodology of the slope stability is done according to 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 Fig. 11.2 Culmann Aproach to Slope Stability 11.3 CULMANN METHOD A technique for the calculation of slope stability based upon the assumption of a plane surface of failure through the toe of the slope has been proposed by Culmann (see Taylor, 1948).

Slope Failure: limited area, steep slope, movement is fast (sometimes with no signs) The stability of a slope should be evaluated when slope movement due to additional FELLENIUS METHOD: This is a modified version of the Method of Slices.

the ground surface, thus not affecting the stability of the slope. The slope is analyzed by Fellenius [10] and Bishop [11] methods of analysis. Fig.1 Geometry of Slope rithm to solve for the factor of safety based on the above-mentioned methods, the forces acting on … Bishop’s method which are higher compare to 1.199-2.688 when using Fellenius’s method. The percentage differences of FOS between these two methods are between 5.25% to 7.33%. For slopes in unsaturated conditions (20 kPa suctions), the FOS are between 1.550-3.702 when 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. Slope Failure: limited area, steep slope, movement is fast (sometimes with no signs) The stability of a slope should be evaluated when slope movement due to additional FELLENIUS METHOD: This is a modified version of the Method of Slices.
