Oasys produces a wide range of geotechnical software which is now being converted from DOS to Windows format to improve the user interface and allow data transfer and manipulation in a variety of formats.
The firm has a number of products for retaining wall solutions, including STAWAL for cantilever walls; FREW for advanced assessment of actual behaviour; and GRETA for gravity walls.
SLOPE examines two-dimensional circular and non-circular slips using a variety of solutions including the Bishop and Janbu methods.The new Windows version offers contouring of the factors of safety as well as flexible graphical input to help the creation of complicated slope profiles.
VDISP calculates settlement or heave under combinations of different foundation loads, sizes, depths and shapes.TUNSET determines three-dimensional displacements and horizontal strains for ground movements caused by tunnelling.
There are four programs covering pile design: PILE calculates the ultimate capacities of the shaft and base and a corresponding pile design load; PILSET assesses the settlement of the pile, including the effects of site loading; ALP analyses the soil/structure interaction of a laterally loaded pile; and DRIVE calculates the stresses and displacements on the axis of a pile during driving.Conversion to Windows will also involve combining PILE and PILSET.
The finite element analysis program SAFE computes two-dimensional problems in plane strain, plane stress and axi-symmetry.
Available material types include linear elastic, water or voids, elastic/MohrCoulomb, modified Cam Clay and Simpson's Rankine lecture soil model BRICK.The firm's steady state seepage program SEEP has been integrated into SAFE as part of the Windows conversion.
