Abstract
Phyllitic and schistose rock masses have a wide range in behaviours during
tunneling. The changes in displacement characteristics are related to the spatial distribution of the
foliation and major geologic structures in the vicinity of the excavation. Direct shear tests were
used to quantify the anisotropic shear strength of phyllites and identify failure mechanisms at the
sample scale. It was found that these observations were also valid for evaluating the rock mass
response during tunneling.
