D-Stability contains three Limit Equilibrium Methods by Bishop, Spencer and Uplift-Van. It supports both drained and undrained material behavior. To facilitate the undrained Shansep analysis, D-Stability allows for staged construction to administrate the yield stress field. The safety factor can be calculated in each construction stage to administrate the safety of a design in time.
D-Stability supports loads and reinforcements. It displays the representative slip circle and alows for detailed inspection of the forces acting upon each slice. This all in a user-friendly interface to enable efficient assessment and design.

D-Stability is currently free to use in its basic package.
The advanced package offers support, an online environment and the former release of D-Geo Stability 18.1.
€370 / FREE Support through Deltares website or, for projects for the Dutch government, through Helpdesk Water.
As of 2020, Deltares offers the D-Stability advanced service package: €648 per year D-Stability application, including: Support through the Deltares online environment. Support through telephone or email. In this service package, Deltares also offers D-Geo Stability 18.1 through the online environment
All technical background can be found in the “Scientific background document” at the left bottom of this page.
Further support will be offered through our advanced service package.
