In early 2021, the eastern wall of the WCP experienced significant displacements after the active mining reached weak diabase sills at the toe of the open pit. Itasca used FLAC3D to back-analyze the open pit slope displacements measured by radar and inclinometers. The use of the IMASS (Itasca Model for Advanced Strain-Softening) constitutive model enables the representation of emergent damage and strength loss, rather than predefining it.
Dr. Lavoine is a young doctor whose expertise is on numerical modeling in geosciences, with a special emphasize on fractured media. He is a graduate engineer in numerical geology and has a PhD in earth sciences from the University of Rennes, France. He has mainly worked on fracture network stochastic and genetic generation methods, and the characterization of their hydraulic and geomechanical properties.
