Slope stability analysis and analysis of soil nailing and reinforced earth walls. Nailing can consist of: Anchors Soil nails, Geosynthetics (reinforced earth), Injection piles


  • Slope and general stability to DIN 4084 and Ec7
  • Analysis after Bishop, Janbu, using the general wedge or vertical slice method
  • Choice of analysis using either partial safety factors to DIN 1054:2010, EC 7, Austrian Standard ÖNORM EN 1997-1 or global safety factors (DIN 1054 old)
  • Consideration of vibrodisplacement compaction after Priebe
  • Stabilisation columns after Neidhart/Gömmel
  • System input using absolute heights
  • 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
  • Soil properties can be selected from an expandable database of common soils
  • Active and passive earth pressure calculation after Culmann is possible
  • Consideration of horizontal and vertical seismic acceleration
  • Consideration of pore water pressures from a pore water pressure line or mesh
  • Import of a pore water pressure mesh created in the GGU-2D-SSFLOW program (groundwater flow modelling)
  • Nailing consisting of geosynthetics (reinforced earth wall) or tension members (modelling of anchors and soil nails) 
  • Automatic generation of nail grids or manual input
  • Geosynthetics can be defined using company products
  • Verification of sliding and overturning safety for nail wall
  • Verification of bearing capacity failure safety to DIN 4017
  • Bending design of the concrete shell to
  • EC 2 via interface to the GGU-SLAB program
  • Punching verification
  • Determination of the maximal ‘nail forces’
  • Analysis with fibre cohesion for wastes dissimilar to soil (Kölsch method)
  • 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
