A complete retaining wall design analyzes wall stability and Global Stability.  One of our recommended software programs for global stability is Gslope!

GSLOPE allows geotechnical engineers to carry out limit equilibrium slope stability analysis of existing natural slopes, unreinforced man-made slopes, or slopes with soil reinforcement. The program uses Bishop’s Modified method and Janbu’s Simplified method. GSLOPE allows either method to be applied to circular, composite, and non-circular surfaces.
