Wedge failure analysis of anchored rock slopes subjected to surcharge and seismic loads
… static and/or dynamic conditions by different methods such as the limit equilibrium method, numerical modeling method, reliability method and stereographic method. However, the anchored rock slope against the wedge failure subjected to surcharge and seismic load has not yet been studied in …

Rapid Drawdown Analysis using the Finite Element Method
… RDD analysis is a multi-stage undrained strength method based on limit equilibrium. The primary objective of this research was to develop a new method for rapid drawdown based on the finite element method. The new method estimates undrained strengths based on effective consolidation stresses from …

Progressive failure of slopes in lined waste impoundments
… on the uncertainties associated with the use of limit equilibrium analyses for evaluation of the stability of slopes in which failure occurs along displacement-softening interfaces. Sliding on such interfaces can occur in a progressive manner with the result that the available interface strengths …

Numerical Modelling of Seismic Activity at Tabular Orebody Mines in South Africa using the Boundary Element Method
… recent efforts to develop and implement these methodologies have been particularly limited in South Africa. This dissertation develops and implements a novel and robust methodology for numerical modelling of seismic activity using the Boundary Element Method and presents several applications at …

Comparative Assessment of Single & Double Interface Shear Strength Properties: A Case Study of a Landfill Project in the Western Cape Province, South Africa
… as they provide a competent hydraulic barrier, limiting environmental pollution and protecting public health. While these inclusions have considerable cost and technical benefits, they have presented several new potential interfaces for shear failure, particularly on side-slopes and basins of …

Reliability Analysis of Tailings Storage Facility Embankments: Investigating the Effect of Zonation on Slope Stability
… bounded between user-defined minimum and maximum limits and can flexibly reproduce a wide range of strength conditions. The distribution parameters were adjusted to reflect different proportions of contractive and dilative tailings, with higher mean φ values corresponding to increasingly dilative …
