Abstract

The discontinuity orientation in foliated or schistose rocks plays a key role in the rock
mass response to the excavation process. In projects where stress induced failure is likely this
influencing parameter should be considered while evaluating the rock mass behavior. For each general rock mass structure there is a characteristic deformation behavior, changes in rock mass quality will increase displacements, while secondary structures influence both the displacement magnitudes and patterns. Two dimensional simulations are able to capture many behaviors, while 3-D simulations utilizing the ubiquitous joint model can capture some of the trends observed for characteristics rock mass structures; however they appear limited in modeling more complex rock mass geometries
