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). 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. 302 Settlement of Piled Foundations.pdf - 1,060 kb Design for Settlement of Pile Groups by the Unified Design Method.

values obtained from each method are almost equal with the difference value is around ± 0.1 as shown in Table 2. 3. Choice of Slope Stability Calculation Method Another important choice, which depends on the means that can be used, is that between a method that models the entire soil mass and a method defined locally,

Fellenius method for slope stability pdf

In the Ordinary Method of Slices (OMS), also known as the Fellenius method, it is assumed that the resultant of the STABILITY OF SLOPES 10.1 INTRODUCTION Slopes of earth are of two types 1. Natural slopes 2. Man made slopes Natural slopes are those that exist in nature and are formed by natural causes. Such slopes exist in hilly areas. The sides of cuttings, the slopes of embankments constructed for roads, railway methods of stability analysis of slopes of finite height 30 31. 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.

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 a typical slice is considered as shown in Fig. 2. . X 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). essential to check the stability of proposed slopes.

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).

Some methods, such as the ordinary method of slices (Fellenius 1927) and Bishop's modified method (Bishop 1955), do not satisfy all condi-tions of equilibrium or even the conditions of force equilibrium.

Analysis of slope stability is very important as many structures in hilly areas failed due to instability of slope. The aim of this study is to determine the factor of safety (FOS) of slopes located at Pahang Matriculation College by using limit equilibrium method. Two methods known as modified Fellenius's method and modified Bishop's method are used in this study.

stress state and its changes cannot be ignored during soil slope stability analysis. method can be regarded subsequently as the enhancement of Fellenius' m The geotechnical engineer frequently uses limit equilibrium methods of analysis when studying slope stability problems, for example, Ordinary or Fellenius' stability calculations and comparisons of Factors of Safety using different methods of limit equilibrium analysis by the method of slices (Bishop, Janbu, Fellenius, (Fellenius) method of limit-equilibrium analysis.

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).
