Abstract
AbstractThe objective of the present work is to study the spatial distribution of safety factors in a vertical purely cohesive cut, utilizing the safety map notion introduced by Baker and Leshchinsky (2001). The investigation shows that there exists a zone in the vicinity of the crest in which critical conditions are realized on slip circles with overhanging cliffs. Such mechanisms are stable only if there is sufficient tensile strength to prevent formation of tension cracks. It is shown that the tensile strength required to prevent cracking is of the same order as the mobilized cohesion, and Taylor's classical result is valid only for such conditions. The safety factor of a vertical cut in a zero tensile strength material is approximately 70% of Taylor's value. It is demonstrated that safety maps provide a natural framework for designing remedial measures in substandard slopes. Copyright © 2003 John Wiley & Sons, Ltd.
