Abstract: Slope design assessments for rock mass failure modes are typically undertaken utilising two-dimensional limit equilibrium (LE) software packages. What happens in scenarios where the design has adopted the recommended slope configuration and still the inter-ramp and overall slope do not meet the design acceptance criteria? This paper presents two case studies within the Pilbara where a three-dimensional LE approach was implemented to further assess slopes that fail to meet the adopted design acceptance criteria, providing an optimal final slope design for implementation.
