Characterizing block geometry in jointed rockmasses

摘要: The intersection of discontinuities in a jointed rockmass creates situ blocks variable three-dimensional (3D) geometry. size and shape rock assembly have dominant influence on the engineering properties rockmass, control, for example failure geometry face optimum associated support surface restraint strategy. distribution block volumes within can be effectively analyzed communicated using cumulative volume curve. Integrated with this analysis, methodology has been developed to characterize volumetric 3D models rockmasses. proposed Block Shape Characterization Method takes into account two factors: first, α, describes shortening minor principal axis while β elongation major axis. When merged distribution, describe classify both distributions any is not limited orthogonal or hexahedra. This polyhedra calibrated based synthetic joint data simulated assemblies. A demonstration given its effectiveness characterizing geometries field mapped fracture data.
