Three-Dimensional Geostatistical Analysis of Rock Fracture Roughness and Its Degradation with Shearing
Three-dimensional surface geometry of rock discontinuities and its evolution with shearing are of great importance in understanding the deformability and hydro-mechanical behavior of rock masses. In the present research, surfaces of three natural rock fractures were digitized and studied before and after the direct shear test. The variography analysis of the surfaces indicated a strong non-line...
متن کاملSurface Roughness Profile Measurement Based on Microscopic Shearing Interferometry
Surface roughness is an important feature of engineering surfaces. For surface roughness profile measurement, most of the exiting methods [1-6] would require isolated conditions to reduce the effect of base vibrations. The scattering interference method [7-8], based on a statistical algorithm together with comparison, may be used in a production environment, but the accuracy and reliability are...
متن کاملFriction and roughness of a melting rock surface
S U M M A R Y Under extreme conditions like those encountered during earthquake slip, frictional melt is likely to occur. It has been observed on ancient faults that the melt is mostly extruded toward local extensional jogs or lateral tension cracks. In the case of laboratory experiments with a rotary shear apparatus, melt is extruded from the sample borders. When this happens, a thin and irreg...

متن کاملShear Strength of Rock Joints Based on Quantified Surface Description
One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...
