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. The Fel- lenius and the normal methods were used in this book to generate stability charts for practical use. The factor of safety obtained by the normal method is the ground surface, thus not affecting the stability of the slope.

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, Se hela listan på hindawi.com methods of analysis when studying slope stability problems, for example, Ordinary or Fellenius method (sometimes referred to as the Swedish circle method or the conven-tional method), Simpli ed Bishop method, Spencer s method,Janbu ssimpli edmethod,Janbu srigorousmethod, Morgenstern-Price method, or uni ed solution scheme [ Fellenius developed a method for stability analysis of a slope assuming a circular failure surface, which is known as the Swedish circle method. Stability Analysis for Cohesive Soil (ɸ U = 0 Analysis): Figure 17.8 shows a slope AB, the stability of which is to be determined. strength reduction method, to verify the code with examples involving a pore water pressure, and to perform the force integration directly in COMSOL using integration couplings. Keywords: Slope stability, finite element analysis, COMSOL Multiphysics, MATLAB script, critical slip surface, shear strength, mobilized shear stress, factor of safety. 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.

Theory of Slope Stability . In the lecture part of this course we will discuss a variety of methods of analysis of slope stability and instability. It is essential that the engineering geologist be intimately familiar with all of these methods because they provide ways of determining, relatively unambiguously, whether a two stages.

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