D-Stability is an analytical tool designed for the determination of safety factors in soft soil embankment cross-sections. It incorporates three Limit Equilibrium Methods, namely the Bishop, Spencer, and Uplift-Van methods. The software can accommodate both drained and undrained material behaviors.

For facilitating the undrained SHANSEP analysis, D-Stability is equipped with a feature that allows for the administration of the yield stress field through staged construction.
