In the companion paper, Travis and co-authors analyse the 301-case database to identify patterns in the factors of safety at failure, failure mechanisms and controlling conditions. They quantify typical “as-built” and “at-failure” factors of safety, the prevalence of circular versus noncircular failures, and the frequency of rainfall and groundwater as primary triggers. The study shows that many failed slopes were originally analysed with simplified pore-pressure or shear-strength assumptions, highlighting the importance of realistic parameter selection and sensitivity analysis.
