Slope failure

Slope stability analysis and analysis of soil nailing and reinforced earth walls.

Nailing can consist of:

  • Anchors
  • Soil nails
  • Geosynthetics (reinforced earth)
  • Injection piles


  • Choice of analysis using either partial safety factors to DIN 1054:2005 or EC 7 or global safety factor (DIN 1054 old)
  • Choice of analysis using Austrian Standard ÖNORM EN 1997-1
  • System input using absolute heights
  • Verification of inner stability after Janbu, using the general wedge method or the vertical slice method
  • General stability to DIN 4084
  • Analysis with fibre cohesion for wastes dissimilar to soil (Kölsch method)
  • Verification of sliding safety
  • Verification of overturning safety
  • Verification of bearing capacity failure safety to DIN 4017
  • Bending design of the concrete shell to DIN 1045-1 via interface to the GGU-SLAB program
  • Punching verification
  • Determination of the maximal "nail forces"
  • Graphics oriented and tabular input/editing of system geometry and system data
  • Import of surface points, pore water pressure points and soil layers from tables (e.g. Excel) via Windows clipboard
  • Automatic generation of nail grids or manual input
  • Geosynthetics can be defined using company products
  • Consideration of horizontal and vertical seismic acceleration
  • Consideration of porewater pressures from a pore water pressure line or pore water pressure mesh
  • Import of a pore water pressure mesh created in the GGU-SS-FLOW2D program (groundwater flow modelling)
  • Encased columns can be generated
  • Variable visualisation of safety factors, e.g. as colour-filled contours
  • Adopted standard, program name and version can be included in the General legend
  • User-defined design of output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
