# 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

INTEGRATED LIMIT EQUILIBRIUM METHOD FOR SLOPE STABILITY ANALYSIS Yalçın, Yağızer M.S., Department of Civil Engineering Supervisor: Asst. Prof. Dr. Onur Pekcan September 2018, 144 pages Limit equilibrium is a well-established concept with successful implementations to slope stability …

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). Moreover, slope stability concerning rainfall and infiltration is analyzed.

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). In Fig. 11.2 the line QS represents a plane potential failure surface.

## Methods of Slope Stability Analysis o Limit equilibrium method o Limit analysis method o Numerical methods We will consider only the limit equilibrium method, since it is the oldest and the mostly used method in practice.

. X IntroductionSince the 1930s, the limit equilibrium (LE) approach has been used to analyse slopes.

Also shown are the free-body diagram and the force polygon for slice i, where 1 i n. 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.

Two methods known as modified Fellenius’s method and modified Bishop’s method are used in this study. where m and n are the stability coefficients. The coefficients m and n are functions of the dimensionless number c'/gH and the depth factor D. Example. Using the Fellenius method of slices, determine the factor of safety, in terms . of effective stress, of the slope shown in Fig.(6) for the given failure surface. few method developed for checking the safety of slopes.

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.

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.

### 16 May 2008 used for slope stability analysis, being relatively simple compared with the safety factor, i.e., ordinary or Fellenius method (Felle- nius 1936)

In this study, 40 kPa of matric suctions was applied in the analysis for both Bishop and Fellenius methods.
