In this paper, double torsion testing of marble specimens has been adopt to determine sub- 1 Introduction critical crack propagation parameters during rock interaction, the morphological characteristics in this In addition to underground tunnels, mine excavations, process were also quantiﬁed while the surface was waste repositories, power station caverns, oil and gas scanned by a three-dimensional high-accuracy non- storage facilities are constructed underground, and contact laser morphology instrument Talysurf CLI most of rock masses exist in water environment. 2000.
