DETAILED FEATURES

  • Spatial variability of material properties aids in improving the calculation of factors of safety
  • Climatic analysis in the unsaturated / vadose zone is available by coupling SVSlope with SVFlux™, or by importing pore-water pressures from SVFlux
  • Rapid drawdown of reservoir levels by the effective stress method is available by coupling SVSlope with SVFlux™
  • Rapid drawdown (RDD) analysis with the Duncan (1990) three-stage total stress method is also available
  • Advanced stochastic analysis such as Monte Carlo, Latin Hypercube, and the Alternative Point Estimation Method allow the end-user to determine normal distributions of the factor of safety as well as the probability of failure
  • Coupled unsaturated steady-state or transient seepage analysis is available when coupled with SVFlux™
  • Advanced critical slip surface searching algorithms including dynamic programming and Greco search methods
  • One- or two-way sensitivity analysis allows the generation of a contoured surface of the factor of safety based on the relationship between two input variables
  • New finite element based slope stability methods
  • Simple and powerful user interface allows rapid creation of effective models in two dimensions
  • 14 different analysis methods including classic method of slices such as Bishop, Janbu, Spencer, Morgenstern-Price, GLE, and others
  • Support for 14 different soil strength models including Mohr-Coulomb, Hoek-Brown, Undrained, Anisotropic, Bilinear, Frictional-Undrained, and four unsaturated shear strength strength models
  • Multiple unsaturated soil strength models allow for more extensive analysis of unsaturated soil conditions
  • Extensive support for reinforced slopes
  • Support for the Hong Kong soil nail equation
  • Representation of dry or wet tension cracks
  • Comprehensive visualization of results

MODEL DESIGN FEATURES

  • CAD style entry of geometry based on AutoCAD™
  • Grid, snapping, and object snapping features available
  • Zooming, panning features available
  • Models stored in XML format for speed and easy data transfer
  • Each surface may have multiple regions defined - Regions are extruded between the surfaces on which they are placed
  • Import AutoCAD™ .dxf geometry and incorporate it directly into the model - node points are automatically aligned with line segment end points
  • Problems may be entered in Metric or Imperial units
  • Initial water table may be graphically drawn on the problem or imported from SVFlux™ as pore-water pressure data
  • A central database of soil properties for all entered slope stability problems is maintained; new problems may draw soils from existing problems (Note: this feature does not require SoilVision®)
  • Problem geometry may be imported from existing problems
  • Colors or patterns of soil regions may be specified
  • Manual entry of region coordinate points
  • Sketch text or lines may be added to the model design
  • Graphical model design may be exported as a WMF or DXF file and/or printed
  • Bitmap or DXF geometry may be imported and layered behind model geometry to simplify model creation

OUTPUT FEATURES

  • Color visualization of the critical slip surface is available via our powerful AcuMesh™ visualization software
  • Color contour plots of any problem variable may be placed on any face of the model; custom color shadings may be specified
  • Color contour plots of all relevant variables
  • Plots may be zoomed to isolate any region of interest
  • Plots of value versus time may be generated at any coordinate for all relevant variables
  • Text and line art may be added to output
  • Graphical output may be exported to WMF, DXF, JPG, or BMP formats
  • Animation of any transient results
