Analysis and design of retaining structures manufactured using concrete elements, stacked blocks and gabions


  • System input using absolute heights
  • Choice of analysis using either partial safety factors to DIN 1054:2005 or EC 7 or global safety factor (DIN 1054 old)
  • Consideration of active and passive berms
  • Consideration of active and passive bounded and double-bounded surcharges
  • Consideration of horizontal area loads
  • Triangular load from stepped loads
  • Analysis using active earth pressure, at-rest ea th pressure and increased active earth pressure
  • Active earth pressure coefficients to DIN 4085 or user-defined values
  • Passive earth pressure coefficients to DIN 4085:2011, Streck, Caquot/Kerisel or user-defined values
  • Verifiction of sliding safety, overturning safety and maximum geogrid forces
  • Choice of analysis of bearing capacity using Danish standard depth coefficient
  • Automatic design of any geogrids present using two-part wedge failure mechanisms
  • "5% condition" test and correction through iterative reduction of shear friction angles that are above the current mean
  • Calculation of settlements
  • Limiting depth analysis using x % of overburden stress, a multiple of the foundation width or as a fixed value
  • Determination of external and internal element stability
  • Seismic effects via additional horizontal loads and/or altered earth pressure coefficients to EC 8 or EAU 1992
  • Analysis of static equilibrium compliant with DIN 1055 or EQU compliant with EC 7
  • Analysis of pull-out resistance of geogrids via gamma(B)
  • Choice of result presentation for earth pressure, moments, horizontal force, vertical force and V · μ/H
  • Interface to the GGU-STABILITY (slope stability nalysis)
  • Adopted standard, program name and version can be included in the General legend
  • Freely definable positioning and sizing of graphical elements and legends
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
