Abstract: This research entailed slope stability analysis of Orapa Mine Slurry Dam 2, located at Orapa in Botswana. The Finite Element (FE) Strength Reduction Technique was used and findings were compared with results from three Limit Equilibrium analysis techniques, namely Bishop Simplified, Spencer’s and Morgenstern-Price methods. The FE analysis was executed using the geotechnical engineering Rocscience software often referred to as Phase 2 or RS2 and the LE analysis was executed using ...
Abstract: An optimum design of box cuts in soil formations is very crucial in order to obviate the major risk factors originating from the collapse of sidewalls and flooding of excavations during storm rainfall. The present paper aims to present a holistic classification of the Kalahari Formation stratigraphy in Zone 5 and define engineering properties of each lithological unit, in order to establish a safe working design. For the present objectives, collection of data was carried out throug...
