GGU-STABILITY

Capabilities:

• 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
