... estimation by Palmström (1996) and the P 32 estimation by Dershowitz (1985). The first one considers the total number of discontinuities in a certain volume weighed by the joint persistence whilst the second method consider the joint area computed by a statistical analysis of the traces under the hypothesis...

... that such a slope was unstable, but in fact such slopes are often observed to be stable. Generally, this stability is attributed to the fact that the discontinuities are not continuous but are of finite size. Thus, as well as joint orientation and the confining pressure, the persistence of a joint has a significant...
