WEDGE ANALYSIS DETERMINE THE FACTOR OF SAFETY OF A TETRAHEDRAL WEDGE THAT MAY FORM IN A ROCK SLOPE GEOTECHNICAL | E03

Summary Wedge Analysis can be used for the evaluation of the stability of soil slopes. It calculates the F.O.S for a tetrahedral wedge that may form in a rock

What makes this module special?

• Deterministic and Probabilistic Analysis • Analysis results grouped on a Calcsheet

Detailed Description A tetrahedral wedge 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 FOS. The probability density function of the FOS is obtained using simulation techniques.

Theory used in this module This module can perform a deterministic as well as a probabilistic analysis. With a probabilistic analysis you can consider variations in material properties and other parameters. Distribution types that can be applied to material properties in a probabilistic analysis include uniform, triangular, exponential, normal, log normal and beta distributions. You can set the number of analysis iterations to be performed and the required probability limit.
