GGU-Cantilever - Geotechnical Analysis Software

Analysis and design of cantilever walls using global and partial safety factor concepts. Among other things, the program simplifies optimisation of spur width and reinforced concrete design.
 

Capabilities:

• 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)
• Berms on the active and passive sides
• Bounded and double-bounded surcharges on active and passive sides
• Analysis using active earth pressure,
  at-rest earth pressure or 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, Culmann or user-defined values
• Choice of hydraulic gradient consideration on active and the passive sides
• Consideration of displacement and action boundary conditions, anchors, struts etc.
• Examines bearing capacity 5° condition to DIN 4017
• Settlement analysis to DIN 4019
• Limiting depth analysis using p % of
  overburden stress, a multiple of footing width b' or a fixed value
• Analysis of overall system stability (sliding, overturning, bearing capacity)
• Analysis of hydraulic heave safety and
  buoyancy safety
• EQU analysis
• Deep-seated stability analysis with
  optimisation of anchor lengths
• Reinforced concrete design and
  crack width analysis compliant with EC 2
• Anchor steel design
• Choice of earth pressure redistributions (among others to EAB 1988 or EAB 2006)
• Choice of result visualisations, among
• others for earth pressure on equivalent wall, water pressure, moments, shear force, normal force, displacement, soil pressure, settlements
• Consideration of pre-stresses and
• pre-deformations
• Seismic effects via additional horizontal loads and/or altered earth pressure coefficients to EC 8 or EAU 1992
• Interface to the GGU-STABILITY program (slope failure analyses)
• Adopted standard, program name and
• version can be included in the General legend
• User-designed output sheet
• Print or copy screen sections, e.g. for
• transfer to a word processor
• Integrated Mini-CAD system for additional annotation of graphics
