- 3D Slope Stability Modelling and its Interoperability with Radar Data by Alison McQuillan, Ph.D., Rocscience Director, Australia and Neil Bar, MEng, Geotechnical Engineer at BHP, Australia
Commercial modeling software has been around for many years now, but when should we model in 3D? and when is modeling in 2D still suitable? In this presentation, Alison and Neil provide case studies on the application of 3D modelling. They talk about the integration of 3D limited equilibrium and 3D numerical modelling results with radar monitoring data. And then show two case studies of the integration of 3D modelling and IDS monitoring data to back analyze two case studies from large open pit mines.
- Excavation Damage Zone Prediction for Deep Repository Engineering Using Discontinuum Modelling by Neda Dadashzadeh, Ph.D., Geomechanics Consultant at RockEng, Canada
The use of deep geological repositories (DGR) is globally accepted to be the best solution for the long term storage of nuclear waste. Construction of the underground spaces within hard rocks induces irreversible brittle damage around the excavation. The prediction of the Excavation Damage Zone (EDZ) is paramount for the design process of DGR, since it can provide a potential leakage pathway for contaminants. Neda’s presentation includes a 2-dimensional Voronoi based numerical study to improve the understanding of the fracture development process associated with EDZs in massive rock masses…
