英文摘要
Mechanical and geometrical properties of rock at grain scale (micro-scale) govern the behaviour of rock-masses at all scales. In recent years several micromechanical modeling techniques (e.g., DEM, FEM/DEM, PFC) have been developed to simulate large scale rock engineering phenomena. Even though these numerical methods use micro-scale input parameters, to date, it does not exist any clear procedure on how to relate them to measured material properties, thus, researchers often use cumbersome numerical procedures to calibrate and verify their models.
