Fracture is a general term used in geology for all kinds of discontinuities caused by mechanical stresses in the bedrock. Fractures include joints and cracks and faults. It is suggested not to use this term in rock engineering and engineering geology. is a plane or surface along which a rock is.

Fractures provide preferential flow paths and establish the internal “plumbing” of the rock mass. Fracture surface roughness and the matedness between surfaces combine to delineate the fracture geometric aperture. New and published measurements show the inherent relation between roughness.

A new laser scanner system is designed and developed for joint surface measurements. Special attention is paid to both surfaces’ matching between upper and lower surfaces. Artificial joint of granite surfaces are measured, processed, analyzed and three dimensional approaches are carried out for.

Knowledge of the spatial distribution of fracture apertures is essential for reliable char-acterization of flow and transport processes in fractured systems and for better under-standing of physicochemical matrix–fracture interactions. Here, we propose and test two image-based methods, thereby.

Attempts have been made to measure aperture as reflected by thickness of infilling of opening mode structures of various kinds (joints, veins, and dikes) to establish a maximum displacement discontinuity-length relationship (Figure 1) (Olson, 2003; Schultz et al., 2008). These authors concluded.
