The Oasys GEO suite is a state-of-the-art suite capable of analysing virtually any geotechnical problem.
The Oasys GEO suite is a state-of-the-art suite capable of analysing virtually any geotechnical problem.
It includes programs in the Windows environment for the analysis of flexible retaining walls, prediction of soil movement and slope stability, pile design and now, with the first release of Safe for Windows, finite element analysis of soils and groundwater.
The finite element program Safe has been used in its Windows format extensively in-house by Arup for the last 2-3 years on high profile projects such as Canary Wharf and the Kings Cross redevelopment.
Safe is a two-dimensional finite element program which uses eight-noded quadrilateral elements.
Its main features include: analysis of plane stress, plane strain or axially symmetric problems; linear or nonlinear behaviour, using a wide range of material models; pore pressures and effective stresses are identified separately, allowing computation for drained or undrained conditions, and time dependent consolidation; incremental loading and changes of material properties, permitting the formation of excavations, embankments etc; extensive graphical input options and in-built mesh generation facility; and a wide range of graphical output and printing facilities.
Other additions for GEO 17.8.4 include some new features in Slope, the well-established slope stability program.
These include: nonlinear strength envelopes for drained materials - power law and hyperbolic relationships; "exploded" slice diagrams and force polygons; and the ability to add text, soil or slip circle labels to graphical output.
Fully functioning 30 day demonstration versions of the programs can be downloaded from the Oasys website.
