Tetrahedral Wedge Analysis

Tetrahedral Wedge Analysis

Stability analysis of a tetrahedral wedge that may form in a rock slope by the intersection of two planar discontinuities, the slope face, and the upper slope with or without a tension crack in the upper slope. The deterministic analysis mode is supplemented by a probabilistic mode to evaluate the effect that the range of input values have on the factor of safetey (FOS). The probability density function of the FOS is obtained using simulation techniques.

Planar Failure in Rock Slopes

Determination of the factor of safety of a planar failure in rock.

Shear Strength of Rough Joints in Rocks

Shear Strength of Jointed Rock Masses

Evaluation of the non-linear shear strength strength vs. normal stress failure envelope that exist in rock masses, some granular soils and some dense sands. Analysis output includes instantaneous cohesion and friction values, and the actual shear strength for a given normal stress.

Shear Strength of Rough Joints in Rocks

Evaluation of the shear strength failure envelope for rough joints in rock. Supported theories include those by Ladanyi and Archambault.
