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.
Why choose GeoStudio?
Rigorous analytical capability.
Sophisticated product integration. Broad application to diverse
geoengineering and earth science problems.
Combine geometries and analyses in a single project
GeoStudio enables you to combine
analyses using different products into a single modeling project, using
the results from one as the starting point for another. Multiple
geometries, including 1D, 2D, and 3D geometries, may also be included in
a single file. 
Draw geometry directly or import CAD files
GeoStudio provides many tools to
define the model domain including coordinate import, geometric item
copypaste, length and angle feedback, region merge and split, and
DWG/DXF file import. BUILD3D, GeoStudio's 3D geometry creation tool,
offers a comprehensive suite of sketch features.

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.

Requires maintenance through June 2021.
New Features in GeoStudio 2021.3
Generalized HoekBrown
The Hoek Brown shearnormal estimation routine in SLOPE/W has been replaced by a HoekBrown material model. The Hoek Brown input parameters (mb, s, and a) can be defined directly or estimated from the rock parameters and disturbance (mi, GSI, and D). A dynamically updated graph allows for visualization of the function as parameters are modified.
Compound Strength
The Compound Strength model is defined by specifying ranges of slice base angles and associating a strength material model with each range. The model is particularly useful for representing jointed rock mass where the strength model for the intact rock is dramatically different from that used to represent the discontinuities. For example, a Hoek Brown model could be used to represent the strength of the intact rock, while a conventional MohrCoulomb model could be used for the joints.
SLOPE/W Solver Improvements
The SLOPE/W solver now implements an underrelaxation technique to improve convergence for trial slip surfaces that are subject to concentrated point loads. One of the most common use cases that benefits from the new underrelaxation technique involves steeply dipping anchors that are part of a tieback wall.
New SIGMA/W Material Models
SANICLAY
The simple anisotropic clay plasticity model (SANICLAY) simulates softening response under undrained compression following Ko consolidation. It allows for the simulation of both undrained and drained rate‐independent behavior of normally consolidated and overconsolidated clays to a satisfactory degree of accuracy. SANICLAY is beneficial for analyzing geotechnical structures constructed on soft clays such as levees, embankments, and dykes.
Hardening Soil Model
The Hardening Soil material model can be used to analyze the behavior of granular, fine grained, and even soft soils. The model can be parameterized using standard laboratory and field tests or empirical formulas. It can be used to simulate strain hardening, dilatancy variations with straining, and nonlinear prefailure stiffness variations. The Hardening Soil model has been proven particularly useful for problems involving excavations into overconsolidated soils.
Improved NorSand Model Definition
The NorSand material model now includes the option to define the initial density using either the void ratio or the new initial state parameter. This improvement makes it possible to easily simulate increasing or constant density with depth. A customizable builtin function has been added, which allows the dependence of the shear modulus on the void ratio to be defined for the material model. The resulting mobilized strength as soils approach their critical state can also now be visualized via new result parameters in the Draw Contours and Draw Graph windows.
Addins Available in SIGMA/W
Addin constitutive models have been reenabled in SIGMA/W. The addin interface has been simplified and the functionality has been improved in two key respects: 1) state parameters can be saved and persisted through time and from one analysis to another; and, 2) plastic states can be set in the addin and painted in the UI to track the evolution of yield and failure zones.
LandClimate Interaction Actual Evaporation Definition Updated
The LandClimate Interaction boundary condition now provides the option to allow for evaporation during rainfall events. This option can lead to reduced deep infiltration in arid and semiarid climates.
New Vapour Density Definition in SEEP/W
Changes in vapour density now account for changes in saturated vapour pressure with respect to temperature.
Seequent ID Licensing Support
Seequent ID support is now available which gives access to cloudbased licensing options, as well as additional GeoStudio resources available on MySeequent. New GeoStudio learning modules are available through Seequent Learning, giving access to GeoStudio courses that can be completed at your own pace.
Additional Interoperability with Leapfrog via Central
Directly connect to a Leapfrog Geological Model through Central to import meshbased topographic or lithology contact surfaces into BUILD3D to use as background geometry or for parametric surface fitting. Import all meshbased surfaces from a Geological Model at once or add one surface at a time. Changes to the Geological Model surfaces can be reloaded into your BUILD3D project, which will automatically update your 3D geometry to incorporate the updated geology.
BUILD3D Improved Parametric Surface Fitting
Import triangle and quadmeshbased surfaces from Central, DXF/DWG, or STL and use a powerful new parametric surface fitting feature that efficiently fits surfaces to large datasets. Multiple surface meshes can be imported simultaneously. The parametric surface fitting feature can also be used to create surfaces from imported point cloud data.
BUILD3D Improved Transformations for Importing/Exporting
Imported meshes and NURBSbased geometry generally need to be rotated, scaled, or translated to conform to the BUILD3D model coordinate system and units. A simple, new transformation tool provides the ability to swap coordinate axes; for example, such that the positive yaxis points upwards. The tool also allows for the translation from a distant datum to a local origin. Transformation settings can be named and reused when importing additional data from the same source location. When exporting surface meshes and STEP file geometry from BUILD3D, the inverse of a named transformation can be applied so the exported BUILD3D model will be transformed to the original coordinate system.
