Created in 2017, Slide3 (formerly “Slide3”) is a new tool that allows geotechnical engineers to calculate the factor of safety of complex 3D slope stability geometries that 2D models cannot fully simulate. Model advanced geometries like landslides, MSE walls, slopes supported by soil nails, and more.

With Slide3, users can calculate failures in any direction without the need for defining the direction in advance, increasing efficiency in modeling and analysis.

Computing large models can take time, but with advanced parallel processing, Slide3 runs analyses over 10x faster than competitors.

Model Creation

The geometry for a Slide3 model can be created and edited in a variety of ways to help Slide3 integrate seamlessly with your current Slope Stability processes.

You can add geometry using the following tools:

  • Import/Export various file formats, including:
    • RS Geometry Object (*.rsgeomobj) Rocscience Geometry object file format)
    • OBJ Files (*.obj)
    • STL Files (*.stl; *.stlbin)
    • Autodesk Files (*.dxf; *.dwg)
    • STEP Files (*.step)
    • IGES Files (*.iges; *.igs)
    • TIN Files (*.tin)
    • ASC Files (*.asc)
    • XYZ Files (*.xyz)
  • Create External Geometry
  • Add Polylines
  • Add 3D Primitive Geometry, such as boxes, cylinders or cones
  • Create Surfaces from Selected geometry
  • Reconstruct Surface from Table values entered by the user
  • Extract Bounding Curve from surfaces
  • 2D Section Export for Slide2 to create a Slide2 file from a plane section of your Slide3 model
  • Planar Section Tool to extract polylines from geometry using a cutting plane

Users can also edit geometry shape by applying the following tools:

  • Extrude/Sweep/Loft operations to add depth dimensions
  • Transform operations such as translate and rotate
  • 3D Boolean operations to combine, remove or divide geometry

Analysis Methods

Slide3 is built on the 2D method of slices (Bishop, Janbu, Spencer and Morgenstern-Price [GLE]) that is the foundation of Slide2. These methods are based on satisfying force and/or moment equilibrium and can be extended to a 3D method of columns, where forces and moments are solved in two orthogonal directions. Vertical forces determine the normal and shear force on the base of each column.

The main assumptions for each method are the same in 2D and 3D:

  • Bishop - moment equilibrium
  • Janbu - force equilibrium
  • Spencer - force and moment equilibrium with constant intercolumn force angle
  • GLE - force and moment equilibrium with intercolumn force function

Designing Supports

Slide3 offers the following support types:

  • End Anchored
  • GeoTextiles
  • Grouted Tiebacks
  • Grouted Tiebacks with Friction
  • Micro Piles
  • Soil Nails
  • User-defined supports

Supports can be applied in any orientation in three dimensions, either as individual bolts or patterns. Orientation options include normal, trend/plunge or vector.

Surface Altering Optimization

Slide3 offers surface altering optimization, a powerful tool that increases analysis speeds and yields lower factors of safety by modifying geometry of a given slip surface. Surface altering optimization uses the results of the primary search method (e.g. sphere or ellipse from Cuckoo Search or Particle Swarm), converts this to a spline surface, and searches for a spline surface with a lower safety factor.

Material Models

Slide3 offers a wide variety of strength models for soil and rock that allow you to model all commonly encountered material types in slope stability analysis. These models include:

  • Mohr-Coulomb
  • Undrained
  • Infinite Strength
  • Anisotropic Strength
  • Shear/Normal Function
  • C/Phi Function
  • Generalized Hoek-Brown
  • Vertical Stress Ratio
  • Barton-Bandis
  • Power Curve
  • Hyperbolic
  • Discrete Function
  • Drained-Undrained
  • Generalized Anisotropic
  • SHANSEP
