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 LEĀ approach was implemented to further assess slopes that fail to meet the adopted design acceptance criteria, providing an optimal final slope design for implementation. }, keywords={geotechnical}, keywords={slope stability analysis}, doi={10.36487/ACG_repo/2135_03}, url={https://papers.acg.uwa.edu.au/p/2135_03_Dwumfour/} }
