Introduzione in Italiano
GeoSlope sviluppa e commercializza
i migliori software CAD per la modellazione geotecnica e geoambientale.
GeoStudio è la suite software che integra tutti i prodotti GeoSlope in un unico ambiente di lavoro (BUILD3D, SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W, CTRAN/W, AIR/W).
Questa suite risponde in maniera completa a tutte le necessità di modellazione geotecnica.
In GeoStudio la definizione del modello viene condivisa tra
i diversi tipi di analisi; per esempio una volta specificata
un'analisi della stabilità con SLOPE/W, è possibile utilizzare
SEEP/W per rappresentare graficamente la geometria senza definirla
di nuova.
Tutti i dati sono ora salvati con la stessa tipologia di file basata sul formato XML; in questo
modo è possibile applicare le diverse analisi agli stessi dati e condividere i risultati
in tutte le analisi.
GeoStudio
è disponibile in quattro versioni diverse per rispondere a
al meglio a ogni tipo di esigenza. Inoltre i software inclusi
in GeoStudio possono essere acquistati anche come pacchetti
singoli.

How SLOPE/W works with other GeoStudio products
Use porewater pressures from SEEP/W, SEEP3D, SIGMA/W, or QUAKE/W
Using 2D or 3D finite element computed porewater pressures in SLOPE/W makes it possible to deal with highly irregular saturated/unsaturated conditions or transient porewater pressure conditions in a stability analysis. For example, you can analyze changes in stability as the porewater pressure changes with time.
Use stresses from SIGMA/W or QUAKE/W
Using finite element computed stresses in SLOPE/W allows you to conduct a stability analysis in addition to a static deformation or dynamic earthquake analysis. For example, you can compute the minimum factor of safety that will be reached during an earthquake, or you can find the resulting permanent deformation, if any, using a Newmarktype procedure.
How SEEP/W works with other GeoStudio products
Dissipate excess porewater pressures generated by SIGMA/W or QUAKE/W
Excess porewater pressures generated by static loading (e.g., fill placement) or by dynamic motion during an earthquake can be brought into SEEP/W to study how long it takes to dissipate the excess pressures.
Use SEEP/W porewater pressures in SLOPE/W
Using finite element computed porewater pressures in SLOPE/W makes it possible to deal with highly irregular saturated / unsaturated conditions or transient porewater pressure conditions in a stability analysis. For example, you can analyze changes in stability as the porewater pressure changes with time.
Use SEEP/W data inside a CTRAN/W model for contaminant transport or a TEMP/W model for convective heat transfer analysis.
Add SEEP3D to SEEP/W to investigate 3D groundwater flow.
How SIGMA/W works with other GeoStudio products
Use SIGMA/W stresses in SLOPE/W or QUAKE/W
Using finite element computed stresses in SLOPE/W makes it possible to conduct a rigorous stability analysis using the same stress values resulting from the deformation analysis. In addition, you can use SIGMA/W stresses as the initial stress state for a dynamic earthquake analysis in QUAKE/W.
Use SIGMA/W porewater pressures in SLOPE/W or SEEP/W
Excess porewater pressures generated by static loading, such as fill placement, can be brought into SEEP/W to study how long it takes to dissipate the excess pressures in the foundation. You can use SLOPE/W to analyze the effect of these excess pressures on stability during construction, allowing you to determine the need for staged loading.
How QUAKE/W works with other GeoStudio products
Use QUAKE/W results in a SLOPE/W stability analysis
Earthquake shaking of ground structures creates inertial forces that may affect the stability of the structures. The shaking may also generate excess porewater pressures. Both the dynamic stress conditions and the generated porewater pressures can be taken into SLOPE/W to study how an earthquake affects the earth structure stability and deformation. SLOPE/W can perform a Newmarktype of deformation analysis to determine the yield acceleration and estimate the permanent deformation of the earth structure.
Dissipate excess QUAKE/W porewater pressures in SEEP/W
Excess porewater pressures generated during an earthquake can be brought into SEEP/W to study how long it will take to dissipate them.
How TEMP/W works with other GeoStudio products
Use TEMP/W with SEEP/W to simulate interactions at the ground surface
Measured climate data can be imported into a coupled TEMP/W and SEEP/W analysis to determine the actual ground surface temperatures with or without snowpack, and actual evaporation rates. TEMP/W will use precipitation data to accumulate snow depths over the winter. An energy balance approach is used to calculate ground temperatures beneath snow and to melt snow during the spring. This information is used by SEEP/W to determine surface ponding, runoff and infiltration.
Use SEEP/W water flow in TEMP/W
An important consideration in a heat transport analysis is water movement, which can be obtained from a SEEP/W analysis. Once this water flow is known, it can be used in TEMP/W to study its impact on heat transfer.
Couple TEMP/W with SEEP/W or AIR/W to perform a density dependent fluid flow analyses.
How CTRAN/W works with other GeoStudio products
Use SEEP/W velocities in CTRAN/W
One of the major components in a contaminant transport analysis is the velocity of the water, which can be obtained from a SEEP/W analysis. Once this velocity is known, it can be used in CTRAN/W to study the transport of contaminants.
Perform density dependent analyses with CTRAN/W and SEEP/W
In density dependent fluid flow, the velocity of the water is dependent on the solute concentration. The water velocity in turn influences the movement of the solute. The iterative transfer of water velocity from SEEP/W to CTRAN/W and the transfer of concentration from CTRAN/W to SEEP/W makes it possible to analyze density dependent fluid flow.
How AIR/W works with other GeoStudio products
Use AIR/W data in TEMP/W
AIR/W and SEEP/W integrate with TEMP/W so that you can model convective heat transfer due to moving air and water. Conversely, you can have the thermal solution affect the air densities and pressures in AIR/W so that the air will flow based on thermal processes alone. AIR/W passes air content and mass flow vectors to TEMP/W and it returns the new temperature profile to AIR/W. All of this happens automatically based on your analysis type definition.
1
Analyse slope stability using piezometric lines
Use
SLOPE/W to do a simple global stability analysis using a piezometric
line to model porewater pressures and the water surcharge load of a
reservoir.
2
Improve PWP definition with seepage analysis
Use
SEEP/W or SEEP3D to do a steadystate seepage analysis and use the
porewater pressures directly in the SLOPE/W stability analysis. This
provides a more realistic understanding of the stability due to the PWP
conditions.
3
Model external loads with stressstrain analysis
Use
SIGMA/W to model load application or removal, and use these stresses
directly in the SLOPE/W analysis, along with the finite element
porewater pressures, to determine the safety factor of the earth
structure.
4 See PWP & stress changes with consolidation analysis
Use
a coupled stress and porewater pressure analysis to simultaneously
model the effect of loading on the porewater pressures and stresses.
Then use the computed stresses and porewater pressures directly in a
SLOPE/W analysis.
5
Model effects of an earthquake
Use
QUAKE/W to consider dynamic loading on the structure from an
earthquake. QUAKE/W can begin with the initial stress and PWP profile
that has already been computed by SIGMA/W and SEEP/W and then apply
earthquake accelerations to model the resulting change in stress. A
Newmark analysis can be conducted in SLOPE/W to determine the cumulative
displacement along the critical slip surface.
6
Model deformation and structure stability
Use
SIGMA/W to redistribute the stresses generated by the earthquake in
QUAKE/W, revealing the settlement that will occur in the earth
structure. Use the final stresses and porewater pressures in SLOPE/W to
analyze stability at the end of shaking.

New Features in GeoStudio 2021 R2
NorSand Material Model in SIGMA/W
The NorSand material model can be used to analyze tailings storage facilities, reinforced earth, and many other classes of geotechnical problems. In keeping with other Critical State Soil Models, the NorSand material model links the stressstrain response of a soil to the void ratio. The NorSand model is able to properly capture the drained and undrained response of loose and dense soils, including liquefaction.
Field Stress Definition Method for In Situ SIGMA/W Analyses
The stressstrain response of a rock mass is often governed by the In Situ stresses produced by a complex geological history. Characterization of these stresses is therefore important for many classes of problems, such as open pit excavations, underground excavations, and tunnelling. Field stresses can now be defined in SIGMA/W as part of an In Situ analysis.
BUIL3D Interoperability Expanded
Improvements were made to importing and exporting in BUILD3D. Imported DXF and DWG files have improved editing capabilities, such that the imported geometry can be easily scaled, translated, or rotated. In addition, surface meshes can now be imported or exported in the DXF file format.
Improved Viewing and Exporting of 3D Results
In hydrogeology studies and coldregion engineering problems, isosurface plots are often required to display groundwater drawdown or depth to freezing in both space and time. BUILD3D now provides the ability to export 3D results from nodal values, such as total head or temperature, or from an isosurface, a geometric object, or the ground surface. This information can be used to build high quality 3D isosurface plots using 3rd party products. In addition, BUILD3D now shows the graph locations in 3D, assisting with results interpretation.
SLOPE/W Reinforcement Libraries Expanded
The manufacturer reinforcement options in SLOPE/W were expanded to include additional products from Huesker and Tensar. Reinforcement products for the Huesker Fortrac® MDT Geogrids (according to EBGEO 2010 and ISO/TR 20432) and the Tensar RE Geogrids (Africa, Asia, Australia, Europe) have been added to the previously available reinforcement libraries. These products were added in partnership with Huesker and Tensar to ensure accurate representation of their products.
Performance Improvements
Optimization to the SIGMA/W and SEEP/W solvers yields analysis times that are up to 3X faster for consolidation analyses.
New Features in GeoStudio 2021
New SIGMA/W Formulation
A completely reformulated version of SIGMA/W is available in GeoStudio 2021. The SIGMA/W solver was upgraded to the GeoStudio Solver Engine that was already available in the GeoStudio flow products. This solver has faster performance, better convergence, and multiphysics integration. The new convergence schemes, combined with a new stressupdate algorithm, allow for the analysis of material nonlinearity that was previously not possible.
Additional In Situ Analysis Method Available in SIGMA/W
SIGMA/W now has two In Situ analysis methods: (1) Gravity Activation, which was previously available; and (2) the K0 Procedure. The K0 Procedure requires that all materials applied to the domain have a valid K0 value. All material models now include a K0 Procedure tab that allows for specification or calculation of the atrest earth pressure coefficient. The relationship used to calculate the atrest earth pressure coefficient depends on whether the soil model has a friction angle or overconsolidation ratio defined, enabling the simulation of a range of stress histories.
SIGMA/W LoadDeformation Formulation Includes PoreWater Pressure Changes
SIGMA/W now incorporates porewater pressure changes in loaddeformation analyses, given the definition of the initial and final porewater pressure conditions. This functionality assists with analyses in which changes in pore water pressure cause complications during construction, but the hydraulic properties are not well known, for example, in deep excavation projects. In addition, SIGMA/W is now capable of analyzing submerged fill placement in loaddeformation analyses, by detecting the presence of ponding at the ground surface and ensuring that the gravity activation procedure uses the correct soil unit weight.
SIGMA/W Consoliation Formulation Updated for Greater Rigour
The new SIGMA/W consolidation analysis formulation can handle complex hydromechanical coupling in both saturated and unsaturated soils. The consolidation formulation considers the bulk modulus of the porefluid, making it possible to simulate fully undrained responses without numerical issues. Convergence settings are now uniquely defined for stressstrain and water flow analyses. Thus, consolidation analyses can evaluate complicated flow systems with the same rigour as SEEP/W.
Strength Reduction Stability Added to SIGMA/W
SIGMA/W now offers Strength Reduction Stability, allowing for the assessment of the safety factor without having to presuppose the shape of the slip surface. Deformation patterns are naturally revealed and soilstructure interactions are rigorously and intuitively handled.
SIGMA/W Material Model Library Expanded Substantially
The SIGMA/W material model library has been significantly enhanced and improved, making it possible to model new classes of problems such as excavations in jointed rock, construction of embankments on foundations that undergo strain hardening or softening, and the undrained behaviour of low conductivity soils. New material models include Hardening/Softening MohrCoulomb, Tresca, Hardening/Softening Tresca, Ubiquitous Joint, and HoekBrown material models. The previous MohrCoulomb model now includes a tension cutoff option and a nonlinear elasticity option was added to all material models except Anisotropic Elastic.
Material Response Types Updated in SIGMA/W
Undrained and drained response types can be combined in a loaddeformation analysis, making it possible, for example, to simulate a free draining material overlying a fully undrained material. In consolidation analyses, the response type is ignored as all materials are assumed to be consolidating. However, a material option was added to designate a material with 'no change in water pressures due to volumetric strain', allowing for the simulation of groundwater flow through all materials in the domain, while ensuring that some materials do not respond to loading/unloading. Finally, undrained behaviour is now simulated using effective stress stiffness properties instead of total stress stiffness properties.
Impervious Structures Added to SIGMA/W, SEEP/W, TEMP/W, CTRAN/W, and AIR/W
The ability to simulate an impervious structure has been added, making it easy to model structures that impede the flow of heat or mass. This new feature removes the need to use interface elements with low conductivity and/or null elements adjacent to geotechnical structures.
Huesker and TenCate Reinforcement Libraries Now Available
The manufacturer reinforcement options in SLOPE/W were expanded to include Huesker and TenCate. Easily define reinforcement representing Huesker Fortrac® T Geogrids and TenCate MiraGrids. The corresponding Tensile Capacity and Overall Reduction Factor are automatically defined given the selection of the manufacturer reinforcement model. This functionality was developed in partnership with Huesker and TenCate to ensure accurate representation of their products.
Import Functionality Expanded in BUILD3D
Importing features in BUILD3D have been expanded to include the ability to import IGES files. AutoCAD models constructed with curves, surfaces, or solids can be imported directly into BUILD3D in the IGES format. In addition, STL meshes are now imported as background geometry in BUILD3D, allowing for the creation of profiles and swept lines on a construction plane while simultaneously snapping to the background mesh. This approach provides a very fast method to construct simplified, clean models of overly complex, overly sampled, or poorly meshed 3D domains, for example from LIDAR scans or Civil3D meshed surfaces.
BUILD3D 2D Section Creation Upgraded
The new plan section tool allows for the creation of sections while in plan view, with infinite and finite length lines. Finite lines can be drawn to create a section through only a portion of the domain, while infinite lines automatically cut through your entire model domain. Lines can be constrained so they are perpendicular to existing features on the plan view, allowing for straightforward creation of 2D crosssections along defined features like a road cut or open pit face.
BUILD3D Definition and Results View Improvements
Many improvements were made to the view features in BUILD3D including persisting camera views and clipping planes in Results View, and the addition of a rotation cube with animation as the cube is rotated. In Results View, BUILD3D now includes the ability to display potentiometric surfaces with elevation contours.
DXF/DWG Import Functionality Expanded
Enhancements to the importing geometry functionality were completed to allow for the conversion of closed loops from DXF and DWG files into regions in GeoStudio. This is common for DXF files exported from Maptek Vulcan geological modelling software.
Manufacturer Reinforcement View Improvements
Properties of manufacturer reinforcements are now displayed in View Object Information and in reports.
