Analysis Type
In CPillar, wedge stability can be assessed using either:
The Analysis Type can be selected in the Project Settings dialog. The required Input Data and analysis results depend upon the currently selected Analysis Type as summarized below.
Deterministic Analysis
In a Deterministic analysis it is assumed that all input parameters are "exactly" known (e.g. pillar dimensions, shear strength, etc.). CPillar computes the factor of safety (FS) for a single pillar. See the Deterministic Analysis topic for more information.
Sensitivity Analysis
In a Sensitivity analysis, individual parameters can be varied between minimum and maximum values, and the factor of safety calculated for each value, and plotted. See the Sensitivity Analysis topic for more information.
Probabilistic Analysis
In a Probabilistic analysis, statistical information can be entered to account for uncertainty in pillar dimensions, shear strength and other parameters. This results in a safety factor distribution from which a probability of failure (PF) is calculated. See the Probabilistic Analysis topic for more information.
