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). 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). The slip circle method of slices is commonly used in the analyses of slope stability and bearing capacity for multi-layered ground.

Applied Geology Flashcards Quizlet

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 Using the Fellenius method of slices, determine the factor of safety, in terms of effective stress, of the slope shown in Figure for the given failure surface using 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).

Limit Equilibrium Methods . Limit equilibrium methods are still currently most used for slopes stability studies. These methods consist in cut- ting the slope into fine slices so that their base can be com- parable with a straight line then to write the equilibrium 2014-08-01 · A case study is analyzed with the finite element method, and the results are compared with outcomes from some of the well-known conventional methods namely: simplified Bishop Method (1955), simplified Janbu method (1954), and Fellenius method (1927).

ABSTRACT: The Fellenius method and the simplified Bishop method are currently applied when analyzing the slope stability of a project design. However, it is well known that large discrepancies exist between the safety factors calculated by both methods, especially in the case of two layer problems where a sandy layer is filled over a clay layer.

HISTORY Petterson (1955) first applied the circle method to the analysis of a soil failure in connection with the failure of a quarry wall in Goeteberg, Sweden. There are other methods of historic interest such as the Culmann method (1875) and the logarithmic spiral method (Rendulic (1935). 31 In the method of slices or the Fellenius method, the sliding mass above the failure surface is divided into a number of slices.

In Fig. 11.2 the line QS represents a plane potential failure surface. The forces acting on the During the next few decades, Fellenius (1936) introduced the Ordinary or Swedish method of slices. In the mid-1950s Janbu (1954) and Bishop (1955) developed advances in the method.
