D-Geo Stability – Bishop and Fellenius

Banner D-Stability 736x190 px

The standard module contains the graphical user interface and an automatic slip circle determination for the lowest safety factor for both Bishop and Fellenius methods. The standard module provides an output report and tabulated and graphical output. Some specific features are:

Geometry input

Graphical user interface.
Geometry wizard.
Arbitrary shaped soil layers (< 499 layers).
Geometry export to Plaxis.

Geometry wizardGeometry wizard

Loading input

Line load (option for load distribution in soil).
Uniform loads (option for load distribution in soil).
Temporary uniform loads (input for degree of consolidation).
Earthquake loads (acceleration).

Soil modelling (drained and undrained behaviour)

Phi and c.
Stress tables (sigma/tau).
Undrained shear strength (cu). Either as values or as a calculated ratio with the pre-consolidation stress.

Input window for stress tables

Soil reinforcement modelling

Sheet-piles (slip circle cannot cross “forbidden” lines).
Geosynthetics.

Modelling of groundwater and water loads
Piezometric head along boundary lines, or layer-by-layer.
Pore pressure induced by loads (temporary/permanent).
Excess pore pressures (pore pressure profile).

Output
Input and output tables, graphs and a report are available for printing, viewing and for export with standard Windows applications through the Windows clipboard. Graphs are available for:

stresses along the vertical
global safety factor
stresses along the slip plane
safety contours
safety grid
chance of failure (with Reliability Analyses module)
influencing factors on soil parameters (with Reliability Analyses module).

D-Geo Stability comes as a standard module, which can be extended further with other modules to fit more advanced applications
