<b>3D Surface Wedge Analysis for Slopes</b><br><br> <i>Swedge</i> evaluates the probability of failure of potentially unstable surface wedges formed in rock slopes. It quickly assesses the effect of rock bolt support on the factor of safety. <i>Swedge</i> is very simple to use, yet allows full 3D visualization of wedges formed by two intersecting discontinuity planes, a slope surface and an optional tension crack. Wedge plane orientations and joint set statistics can be read into <i>Swedge</i> from a <i>Dips</i> file. <br><br>For a comprehensive program overview, including a description of available features and options, see the <a href="http://rocscience.com/help/swedge/webhelp/Swedge.htm">Online Help</a>.
- What is the meaning of Area (Slope) in the wedge information list?
- Why might water pressure cause a decrease in Factor of Safety as the slope angle decreases?
- Why does the persistence analysis option affect the probability of failure?
- Why might a small change in applied force result in a considerable change in factor of safety?
- Why might a very small tension crack have a strong influence on factor of safety under saturated conditions?
- Why, in some cases, does a small increase in percentage filled for a fissure cause a dramatic drop in factor of safety?
