“…After the 3-D scanning, the digitized data were exported in xyz file format to estimate the JRC. The surface roughness parameter, Z 2 , the root-mean-square of the slope of a 2-D profile is widely used to correlate with JRC value (Jang et al, 2014;Tatone & Grasselli, 2012;Tse & Cruden, 1979;Yang et al, 2001;Yu & Vayssade, 1991). For a 2-D profile, Z 2 is given by the following:…”

“…The hydraulic behavior of a blocky rock mass is more dependent on the characteristics of the system of fractures within the rock mss than the characteristics of the intact rock, and fractures represent conduits of enhanced hydraulic conductivity relative to the intact rock (Tatone, 2012). Therefore, the analysis of fluid flow through a single rough fracture has become a hot focus in many research areas, such as oil recovery, geothermal energy extraction groundwater flow and the underground disposal of CO 2 and radioactive waste.…”

“…The limitation of this kind of method is that the fracture surfaces are destroyed after measurement and the fracture cannot be used for any other testing. Recently, as non-contact techniques, such as triangulation method (Lanaro 2000, Grasselli 2002, Tatone & Grasselli 2009), laser scanning (Fardin 2004, Xia & Wang 2008, are widely employed to measure surface topography, methods named as referenced noncontact surface topography measurements (Tatone, 2012) are developed to measure the aperture distribution of a fracture (Brown & Scholz 1985, Lanaro 2000, Wang 2009). These methods are proposed to measure the fracture aperture indirectly based on the surface topography of the two fracture walls.…”

“…A wide spectrum of measurement techniques, targeting different observation lengths, has been developed over the last 50 years. This includes: (1) contact methods such as the Barton comb (Morelli, ) and the stylus profilometer (Poon and Bhushan, ); (2) atomic force microscopy (Thom et al., ); and (3) non‐invasive optical techniques such as confocal microscopy (Ficker and Martišek, ), white‐light interferometry (Renard et al., ), laser triangulation (Martínez et al., ), structured light projection (Tatone and Grasselli, ) and photogrammetry (Lee and Ahn, ). The lateral and vertical resolution and accuracy of the measurement techniques depend on the underlying physical principles; each technique therefore has its own restrictive application range.…”
