GeoStar supports standard and improved limit equilibrium methods. Cylindrical or general shaped (polygonal) shear surface. Progressive failure.
MZ Associates Ltd has ceased trading. Mark Zytynski, the author of the packages SID and STABLE will continue to support these systems on an informal basis. SID and STABLE are available for download free of charge from this site.
GGU-SLICE calculates the stability of slope laminae. Colour output and bitmap graphics are supported.
GGU-STABILITY for slope failure calculations and soil nailing. Considers circular slip surfaces (Bishop or Krey) and polygonal slip surfaces (Janbu),…
GSLOPE carries out limit equilibrium slope stability analysis of existing natural slopes, unreinforced man-made slopes, or slopes with soil reinforcement.
GSTABL7 with STEDwin v.2 is a 2D limit equilibrium slope stability program based on STABL6 but which includes geogrid reinforcement, piers/piles, tiebacks, soil nails, applied forces, and surcharge loads.
I.L.A. is a slope stability analysis program that also incorporates features for retaining system designing.
Uses the DLO method to quickly, easily and accurately analyse geotechnical stability problems of almost any type – including combined problems simultaneously involving slope stability, retaining walls, footings and tunnels.
LISA (Level I Stability Analysis) uses Monte Carlo simulation of the infinite slope equation to estimate a probability of slope failure for use in relative stability assessment of natural slopes.
