... parameters method (i.e. the dimensionless asperity angle and the dimensionless asperity area) has been proposed. And the physical and mechanical meanings of the two parameters have been analyzed, those two can combine the geometry characteristic, the mechanical and hydromechanical properties, also can better...

...). In 2005, a part of the geometry was captured using the 3D laser- scanning technique for the DECOVALEX IV project. Furthermore, in 2006, the BGR borehole seismic equipment was tested in a section of the tunnel with the aim to estimate the extent of the EDZ in the tunnel (Schuster 2007). All...

... of hydraulic fracturing is in most cases directly dependent upon the fracture geometry created in a layered reservoir. However, there is no existing reliable method to accurately measure fracture geometry, especially the fracture width, during and after hydraulic fracturing treatments. Hence, the modelling...

... OF 3D IMAGES 2.1 Background A 3D image is a combination of a real (digital) photograph with the geometric information on the objects it shows. In the actual cases the objects are rock faces and walls. The geometry of the exposed rock mass can be reconstructed from digital images using methods...
