Abstract
Block theory has been well applied to solve practical problems in rock engineering associated with the stability of discontinuous rock masses. Traditional methods of block theory are difficult to determine the actual locations of blocks, and they are always limited to the analysis of convex blocks constructed with relatively few discontinuities that are assumed to be infinitely persistent. However, the occurrence of finite discontinuities including joints and faults can produce numerous blocks with not only convex but also concave geometries. In order to overcome these shortcomings, a new block visualization technique based on the stereo-analytical method is introduced to systematically describe block geometries. The proposed visualization method would provide basis for computer modelling and mechanical calculating of large-scale rock mass systems. Furthermore, examples of a slope excavation and a tunnel excavation in rock masses are presented to prove the validity and high performance of this methodology.
