Realistic simulation of challenging rock engineering problems THE CHALLENGE Conventional numerical methods used in rock engineering suffer from several limitations. Traditional continuum methods based on shear strength criteria do not correctly capture stress-driven fracturing in hard rock. Furthermore, these methods have limited ability to account for the translation, rotation, and interaction of rock blocks along … Read more
Underground excavations in a jointed rock mass THE CHALLENGE Prediction of rock fracturing around underground excavations accounting for in-situ stress anisotropy, excavation geometry, and rock mass conditions. Discontinuous rock mass fabric characterized by joint sets. Complex interaction between excavation-induced stresses, rock mass discontinuities and rock support members. Determination of rock bolt pattern and spacing as … Read more
