| dc.description.abstract | The representative elementary volume (REV) of a jointed rock mass can be determined using finite numerical analysis, but the effect of using different finite element model settings has not been widely studied. This paper aims to compare various finite element codes and their settings for determining the REV size of an excavated jointed rock mass. We used the scriptable, free program ADONIS and Rocscience's RS2 and RS3 to numerically analyse circular excavation in a rock mass intersected by orthogonal joint sets with specified joint spacing. While the determined REV sizes versus the opening diameter to joint spacing ratio are generally comparable for all analyses, the use of XFEM in RS2 results in a relatively larger REV size. Considering computation efficiency, a 2-dimensional, efficient, and representative finite element model for a complete range analysis to obtain a reliable REV size of a jointed rock mass is preferred over a 3-dimensional analysis. | |
