GEO5 Abutment program is used to design bridge abutments including wing walls. It allows checking the abutment for overturning, translation, bearing capacity of foundation soil and dimensioning of decisive or reinforced concrete sections (including wings). The main GEO5 Abutment program features are:
- Verification analysis can be performed employing EN 1997-1, LRFD or classical approach (limit states, the factor of safety)
- EN 1997 – option to choose partial factors based on National Annexes
- EN 1997 – option to choose all design approaches, consider design situations
- A large number of possible wall shapes
- Check of concrete cross-sections according to various standards (EC 2, BS 8110, IS456, CSN, PN)
- Design of wing walls
- Generally a layered soil environment
- Built-in database of soil parameters
- Arbitrary number of surcharges applied to structures (strip, trapezoidal, concentrated load)
- Arbitrary number of inserted forces (anchors, safety fences, etc.)
- Modeling of water in front of and behind structures, modeling of artesian water
- Analysis of internal stability (overturning, slip, bearing capacity of foundation soil)
- Verification of construction joints and wall keys
- The general shape of terrain behind the structure
- Front face resistance in front of the structure (at rest, passive, reduced passive)
- New types of the foundation below the abutment (strip footing, piles)
- Berms in front of the structure
- Calculation of earth pressures in effective and total parameters
- Earthquake effects (Mononobe-Okabe, Arrango, Chinese standards)
- Multiple construction stages
