Overview of Input Data

SWedge computes the factor of safety for the sliding of a wedge formed in a rock slope by:

  1. The slope plane,
  2. The upper slope (bench) plane,
  3. Two joint planes,
  4. A basal failure plane (optional), and
  5. A tension crack (optional).

At an early stage in the solution process, SWedge checks if the geometry of a model is valid, before proceeding to calculate a Safety Factor or Probability of Failure for a sliding wedge.

To enter model parameters, select the "Input Data" toolbar button or Analysis > Input Data from the menu. This opens the Input Data dialog. This dialog allows you to define the following model input parameters:

Slope Angle , Slope Height, Unit Weight

Upper Face Angle , Bench Width Analysis (optional)

Joint Plane Angle , Waviness

Joint Plane Angle Strength

Tension Crack Angle , Location (optional)

Water Pressure

Seismic Coefficient

External Force
