7. 7
• Slope stability / Macrostability (mature)
• Settlement (prototype)
• Ground water flow (in development)
• Backwards erosion / Piping (in development)

• Small, agile programs
• Development in "fixed time", with a variable in scope
• Fast
• Robust
• Precise
• Optimized for scripting
• Integrated probabilistics

Basic Kernel phreatic water integration stab
1st release
1st release Probabilistic
integrate

How to get from prototype to
• Settlement
Basic Krnel phreatic water integration stab
1st release
1st release Probabilistic
integrate
So, we can program it later in the development of the Suite

What can it do ?
Initial (stage)
soil surface
added soil layers
calculation vertical
> calculate vertical settlement of soil, where:
 In the initial stage multiple soil layers can be considered;
 Per stage, a change in loading conditions in time (new layers) induces consolidation of the initial stage;
 The Isotache models (NEN-Bjerrum / abc) can be used;
 The OCR can be given (per layer) and
 The boundaries are considered drained and Darcy formulation is applied;
 Only 1 vertical is considered, so stresses do not spread in horizontal direction (no horizontal deformations);
 Results of the vertical settlement and stresses are shown as function of depth and time;
 Unloading and a phreatic level outside the geometry are possible to define in the interface, but not considered in the calculation.

17. 17
Testing
> calculate vertical settlement of soil, with the following requirements
• FAST: < 60 s
• ROBUST: no convergence errors (1D)
• PRECISE: match with old D-Settlement (<5%)
