CLU_STAR

Cluster and rock mass stability analysis.

The programme has been designed to offer complete support for geomechanical calculations.

In the first phase it allows filing, calculation and graphical representation of geological structures.

Cluster analysis, otherwise known as the recognition of joint families, is carried out by a procedure of pole aggregation similar to that used in multivariate analysis.

These procedures are designed to operate directly on the collected data instead of on their statistical distribution, this allows results much nearer to the geomechanical reality to be obtained.

The increased interactivity offers the operator much better control of the full sequence of operations, since it is possible to choose the level of aggregation, and hence the dimension of the cluster, as well as the algorithms for the assignment of the joints to the individual families.

The programme identifies therefore the rock wedges and determines their safety factor, also when external loads and rock bolts are present; besides this, the principal components of the hydraulic conducibility of the rock mass can be appraised.

The graphic output includes the star diagram of the dip directions and the stereographical polar projection (equal area, Schmidt net or equal angle, Wulff net, on the upper or lower hemisphere) of the original joints as well as the families found.

Optionally circle arcs, wedge safety factors, front and friction angle can be added to the plot.

All input and output data can be printed in text form.
