New LimitState:GEO Application / Technical Notes
The flexible tools available within LimitState:GEO allow not only standard soil collapse problems to be modeled, but a broad range of soil-structure interaction problems. Capabilities include:
- Modeling soil/structure interface properties
- Modeling tension cracks in soil and at soil/structure interfaces
- Plastic bending and shear failure of structural elements such as cantilever walls
- Modeling of gabion walls, including behavior of individual gabions
- Modeling soil reinforcement, including reinforced soil walls with facing panels
In the coming months, a range of application notes will be appearing on the LimitState website that cover, in detail, the modeling of the above. Just visit the application specific pages that are linked from www.limitstate.com/geo
Application notes already available include:

Also, to supplement the Application Notes, a series of associated Technical Notes will also be appearing that cover underlying principles and theory.
Example - Retaining Walls
The most recent Application Note, LS-G-AN3 on Retaining Walls, describes the typical steps followed in setting up and analysing a gravity retaining wall stability problem with LimitState:GEO. It also describes the analysis of a trench excavation in front of the wall:
Download LS-G-AN3, the gravity wall application note. Within the document, the key concepts of 'soil/structure interface properties' and 'cohesive soil/structure interface tensile strength' are discussed.
