corresponding estimates of the stability factor have been plotted against n in the same gure. It can be observed that these numerical estimates decrease with the number of intersecting joints down to the estimate produced by the homogenization approach. The observed discrepancy between homogenization and direct approaches, could be regarded as a ‘‘size’’ or ‘‘scale effect’’ which is not included in the classical
homogenization model. A possible way to overcome such a limitation of the latter, while still taking advantage of the homogenization concept as a computational time-saving alternative for design purposes, could be to resort to a description of the fractured rock medium as a Cosserat or micropolar continuum, as advocated for instance by Biot (1967); Besdo(1985); Adhikary and Dyskin (1997); and Sulem and Mulhaus (1997) for strati ed or block structures. The second part of this paper is devoted to applying such a model to describing the failure properties of jointed rock media.
