An extensive program was conducted to develop and validate computer models for the deformation of structures in jointed rock. Both discrete element and "nite element models were investigated. The program comprised a sequence of seven calculational and experimental studies. In the "nal step, model pr
## Abstract Numerous studies have been made to improve Barton's shear strength model for the quantification of rock joints. However, in these previous studies, the roughness and shear strength of the rock joint have been underestimated especially for relatively high undulated profiles (joint roughn
An equivalent continuum model of rock mass consisting of joints and rock is proposed by averaging the stress and strain in a volume element. Using the theory of damage mechanics and fracture mechanics, the damage tensor, effective stress tensor, damage strain, etc. of the rock mass are defined, prop
