In this paper, a comprehensive model for the behavior of jointed rock masses reinforced by passive, fully-grouted rock bolts is presented. The model is based on an “equivalent material” approach in which the influence of rock joints as well as rock bolts is distributed throughout the rock mass. A typical problem of a jointed rock slope has been analyzed and factors of safety against collaspse have been computed using the Finite Element Method. It is shown that the dilatancy of rock joints and the orientation of rock bolts are the most important factors in determining the effectiveness of passive, fully-grouted rock bolts.
