2021-01-27 2019-05-01 Lecture capture on slope stability, Ordinary Method of Slices and Modified (Simplified) Bishop's Method. reliability of the numerical result for slope stability analysis by the finite element SSR technique, its comparison with the well known conventional methods namely Bishop Method (1955), Fellenius Method (1936) and Spencer Method (1967) is shown for homogeneous and layered soil. Good agreement is found between the The speci c assumptions made are features of the speci c method; for example, the Fellenius and the modi ed Bishop methods use di erent sets of assumptions. In this handout, we will focus our attention on these two methods.

Fellenius Method. The majority of slope stability problems are statically indeterminate, and, as a result, some simplifying assumptions are made for the sake of determining these problems.

2020-12-23 Fellenius/Petterson Method Verification of the Stability of the Slope The slip surface was determined. In this case the slip surface is determined by a circle with its centre at point O > x, z@ > 13 5279;18. 9443@ and a radius R 15.00 m. Points Z sp and K sp indicate the beginning and end of the slip surface.

It ignores all the inter The slope stability analysis is crucial in engineering practice to ensure the stability of structures and prevent loss of human life and money. The common methods for the analysis of a slope’s stability are Culmann Method, Ordinary Method of Slices and Bishop Method of Slices.
