How SLOPE/W works with other GeoStudio products

Use pore-water pressures from SEEP/W, SIGMA/W, or QUAKE/W

Using finite element computed pore-water pressures in SLOPE/W makes it possible to deal with highly irregular saturated/unsaturated conditions or transient pore-water pressure conditions in a stability analysis. For example, you can analyze changes in stability as the pore-water 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 Newmark-type procedure.

 

How SEEP/W works with other GeoStudio products

Dissipate excess pore-water pressures generated by SIGMA/W or QUAKE/W

Excess pore-water 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 pore-water pressures in SLOPE/W

Using finite element computed pore-water pressures in SLOPE/W makes it possible to deal with highly irregular saturated / unsaturated conditions or transient pore-water pressure conditions in a stability analysis. For example, you can analyze changes in stability as the pore-water 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.

 

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 pore-water pressures in SLOPE/W or SEEP/W

Excess pore-water 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 pore-water pressures. Both the dynamic stress conditions and the generated pore-water pressures can be taken into SLOPE/W to study how an earthquake affects the earth structure stability and deformation. SLOPE/W can perform a Newmark-type of deformation analysis to determine the yield acceleration and estimate the permanent deformation of the earth structure.

Dissipate excess QUAKE/W pore-water pressures in SEEP/W

Excess pore-water 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.

 

GeoStudio Integration Workflow

Use SLOPE/W to do a simple global stability analysis using a piezometric line to model pore-water pressures and the water surcharge load of a reservoir.

Use SEEP/W to do a steady-state seepage analysis and use the pore-water pressures directly in the SLOPE/W stability analysis. This provides a more realistic understanding of the stability due to the PWP conditions.

Use SIGMA/W to model load application or removal, and use these stresses directly in the SLOPE/W analysis, along with the finite element pore-water pressures, to determine the safety factor of the earth structure.

Use a coupled stress and pore-water pressure analysis to simultaneously model the effect of loading on the pore-water pressures and stresses. Then use the computed stresses and pore-water pressures directly in a SLOPE/W analysis.

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.

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 pore-water pressures in SLOPE/W to analyze stability at the end of shaking.
