Theoretical analysis of the stability of slopes

Abstract: The problem of limiting equilibrium of a slope in a state of plane strain is formulated in terms of the variational calculus. Formulated that way, the analysis is carried out without any a priori assumptions with respect to the shape of the slip surface, or the normal stress distribution along it. Thus, on the basis of only a formal definition of the concepts of limiting equilibrium, and factor of safety with respect to strength, it is proven that the minimal factor of safety must occur on slip surfaces with a… Show more

“…Baker and Garber (1978) used the calculus of variations to locate the critical failure surface and thereby calculated the minimum factor of safety. With the advent of high performance computers, use of optimization techniques is becoming an effective means of finding the critical failure surface.…”

“…Such a problem can be solved as a standard isoperimetric problem, to render the minimum value of (i.e., the factor of safety s ). As presented by Baker and Garber [24], using the variational calculus principles can find a pair of functions ( ) and ( ) to determine the factor of safety. The details of the variational derivation can be found elsewhere [20,24,25].…”

“…This effect causes an increase in shearing stress within the slope body, deteriorating the original cracks within the native land structure and simultaneously generating new blast cracks; thereby influencing slope stability. Baker and Garber (1978) [7] proposed a static calculation method to evaluate the stability of slope under dynamic loads. Cherles (1988) [8] [9] employed software to simulate the transmission conditions of blast waves in the soil, investigating the spectral properties of blast waves and their effects on the building structures.…”
