Abstract: Columnar jointed basalt shows highly anisotropic characteristics in strength and deformation modulus,and hence,understanding its physical and mechanical properties is of great significance to engineering safety.According to the natural structural characteristics of columnar jointed rock mass,a three-dimensional polycrystalline discrete element model including double joint networks was established. Using this model,the mechanical properties and failure modes of columnar jointed rock mass under un... More
