Novapoint GS Stabilitet

Powerful interface

By using cross sections with soundings as templates, the definition of the soil geometry is simple and fast. The soundings do not only give points in the soil where different soil layers are located. They also give input to the table of material properties for each soil layer. The user interface performs automatic control of the geometry – ensuring that the layers do not intersect.

Profiles

Profiles are a unique feature to represent the variation of undrained shear strength and pore water pressure in the soil layers. Any state of these properties can be simulated. The user gives the variation graphically by defining points in a section with a given parameter value. By plotting isolines for the resulting state gives good control of the achieved model. Profiles may be combined with other contributions like constant shear strength or hydrostatic pore water pressure from a defined ground water level.

Stabilizing structures

If needed stabilizing actions of the soil can be modelled. This can be achieved in three different ways using:

• Automatic procedure for calculation of needed height of banking.

• Simulation of lime cement blocks in the soil volume.

• Soil nails.

Solution methods

The solution methods within GS Stability are: Beast (two different models based on Morgenstern-Price) and Simplified and modified Bishop. By using any Beast model the Swedish combined method may be used – easily selected by a checkbox. Within friction materials the drained shear strength may be modelled by giving a percentage of the undrained shear strength.

Presentation of results

The results from the analysis are presented, in addition to the critical shear surface, in a graphical diagram. The diagram shows the forces, moments and shear forces used within the solution for the critical shear surface. A complete documentation of input data and the results from the analysis, including graphics, may be printed out and saved as a calculation report.
