Description CPillar (3.0) is an analysis tool for evaluating the stability of surface or underground crown pillars, and laminated roof beds. Analysis methods include rigid or elastic analysis and voussoir (no tension) analysis, for pillar, beam or plate configurations. It provides an integrated graphical environment for data entry and 3D model visualization. A CAD based modeler allows for point and click data input and editing. Popup windows allow for entry and modification of input parameters. Statistical analysis of failure probability can be carried out by entering standard deviations for material and loading parameters. Strength Criteria: Hoek-Brown; Mohr-Coulomb; Hoek-Brown (RMR) - m and s constants calculated from rock mass rating and intact m value. Geometry: Surface/underground crown pillars; Roof beams (long excavation); Roof plates; Overburden; Water height. Failure Modes: Rigid - shear at abutments; Elastic - shear at abutments and elastic buckling; Voussoir - shear, arch snap-thru (gravity buckling) and crushing. Lateral Stresses: Constant; Gravitational. Statistical Analysis: Enter standard deviations for material and loading parameters to obtain mean safety factors and failure probabilities. Analysis Methods: Rigid Analysis; Elastic Analysis; Voussoir analysis. Printer Support: HP Laserjet, Paintjet & Deskjet ; Epson 9 and 24 pin. Miscellaneous: Automatic calculation of rock mass modulus from rock mass rating; Specify dip angle and support pressure for voussoir analysis; Full screen / cropped image capture direct to PCX file or printer; Improved and updated reference documentation, including examples section.
Cost US Dollars 195.00 (Canadian customers Can Dollars 195.00)
