Abstract
Rock fracturing is a hot issue in rock engineering. The macroscopic fracture development is associated with the microscopic damage evolution. Therefore, this research investigated the failure mechanism based on multi-scale analysis methods, including micro-scale (grain scale), meso-scale (laboratory scale), and macro-scale (field scale). This research combined the microscopic data and laboratory-scale mechanical properties to create a valid field-scale model based on the comparison with the in-situ data.
