Input Data Overview

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
