Abstract
Mica schist of the Wissahickon Formation is tested in tension and compression in order to investigate the nature, causes and effects of friction and intrinsic shear strength (cohesion) and their relation to the compressive strength of this metamorphic rock. The fracture surfaces are examined with the aid of a scanning electron microscope. Special consideration is given to the contribution of foliation planes, which are considered sources of weakness.
Shear strength parameters are shown to be a function of confining pressure and petrographic characteristics of the sample. Orientation of weaker foliation planes also has a demonstrable effect on the parameters, which have minimal values when foliation planes are oriented at approximately
55° from the horizontal.
