Janbu’s method 5. Friction circle method 6. Taylor’s stability number method 7 The stability of earthworks (cuttings, embankments, dikes) and natural slopes is a?problem that is of concern to geotechnicians, both practitioners and researchers. The disorders generated by breaking the slopes are usually spectacular, often destructive and sometimes murderers. Many methods of calculating stability have been proposed. These are differentiated?by the assumptions accepted by Irrigation Engineering Multiple Choice Questions on “Stability of Earthen Slopes”.

IOP Conference Series: Materials Science and Engineering PAPER • two stages. In the 1st stage the stability of the slope is calculated and in the 2nd stage the stability of an anchored slope is calculated. The slope stability is calculated using Fellenius/Petterson method and Bishop’s simplified method (the circular slip surface). 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).

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.

In this study, 40 kPa of matric suctions was applied in the analysis for both Bishop and Fellenius methods. From the analysis, the results indicate that the Ordinary Method of Slices or Fellinius Method for. Soils with @ = 0 o r @ > 0. Wedge Method for Soils with@ = O o r @ > 0.

The verification methodology of the slope stability is done according to 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 Fellenius method, based on the concept of submerged weight and hereafter called the normal method (Bailey and Christian, 1969), is available.
