CLU-STAR
is a program for computerised structural geology data collection
and analysis.
The program recognises the discontinuity sets of a rock mass through
hierarchical and non-hierarchical clustering procedures derived
from the multivariate analysis.
These
clustering procedures operate directly on the collected data instead
of on their statistical distribution; the results are consequently
closer to the geomechanical reality.
The
high interactivity of the program offers the operator a better control
of the full sequence of operations, as it is possible to choose
the clustering level (and hence the dimension of the clusters),
as well as the algorithms for the assignment of the joints to the
individual discontinuity sets.
Once
the joint sets have been determined, the program calculates the
safety factor of the rock wedges, considering water pressures, surcharges,
rock bolting and seismicity.
 The
program can also evaluate the anisotropic permeability tensor of
the rock mass.
Different
outputs are produced both in graphical and tabular form:
- the
printout of the structural geology data collection sheets;
-
the projection of the originally collected joint poles onto the
stereonet;
-
complete projection of the results of the cluster analysis: the
joint sets, the great circles, the rock wedge safety factors,
the slope face and the friction angle circle can be represented
on the stereonet;
-
a rose diagram for the evaluation of the dip direction distribution
