Introduction

Slope stability is a major design objective in civil and mining projects such as dams and open pit mines. Stability of slopes is evaluated primarily based on the factor of safety, defined as the factor by which the shear strength of the slope material must be divided to bring the slope to the point of failure. It is evident from the definition that factor of safety is controlled by shear strength of the material. Failure criteria describing material strength under various loading conditions are used in stability analysis to determine the slope factor of safety.

The linear Mohr–Coulomb and nonlinear Hoek–Brown criteria (Hoek and Brown 1980, 2018; Hoek et al. 2002) are by far the most commonly used failure criteria in slope stability analysis. As a result, there are many instances in which it is desirable to convert one criterion to another without significantly affecting the results of analysis. It is crucial at this point to make a distinction between conversion methods...
