... on artificial block-in-matrix rocks. Tunneling in weak rock mass is often accompanied by large displacements, hence an intended issue was to investigate the behavior of BIM-rocks exposed to large strains. Lindquist (1994) provided a comprehensive study of triaxial tests on artificial BIM-rocks. However, being...
