3D Surface Wedge Analysis for Slopes
version 5.0
Swedge 5.0 is a quick,
interactive and simple to use analysis tool for evaluating the geometry and
stability of surface wedges in rock slopes. Wedges are defined by two
intersecting discontinuity planes, the slope surface and an optional tension
crack. Swedge provides
an integrated graphical environment for fast, easy data entry and 3D model
visualization.
Swedge 5.0 offers an extensive
array of analysis options including Deterministic, Probabilistic, Combinations,
Sensitivity, and Persistence analysis.
For a Deterministic analysis, Swedge computes
the factor of safety for a specific wedge. For a Probabilistic analysis,
statistical input data can be entered to account for uncertainty in joint
orientation, strength and other parameters, and a probability of failure is
calculated. For a Combination analysis, any number of joint planes can be
defined, and Swedge will
compute all possible combinations of joint intersections which can form a wedge.
Rock bolts, shotcrete or support pressure can be applied to increase the wedge
safety factor. De-stabilizing forces due to water pressure, seismic loads or
external forces can also be easily modeled. Joint shear strength options include
Mohr-Coulomb, Barton-Bandis or Power Curve models, and a joint waviness angle
can be defined.
Swedge 5.0 provides improved
integration with the Dips program.
A complete Dipsfile
can be imported into Swedge and
analyzed with the Combination analysis option; or statistical joint set
information (Fisher Distribution) can be imported for a Probabilistic analysis.
Dips is a program for the
graphical and statistical analysis of structural geology data using stereonets; click
