Latest Features in Settle3

2D Section Creator

Settle3 Section Creator
Settle3: Section Creator

In the coming months, Settle3 is introducing a new tool for defining the material layers of your model – the 2D Section Creator. Currently, users create their material layers in one of two ways: they either create the layers as constants across all depths or they use boreholes to define layer depths and interpolate in between. With the new Section Creator, users can create a unique 2D section and then extrude that section to create their 3D model. The tool gives users more control over how they draw and define their soil profile. Users can even integrate borehole data to use as guides with the material layers of the section, giving them more granular control over the material layers.

Like with all Rocsience features, the new Section Creator will be accompanied by a new step-by-step tutorial to help users learn the basics and start using the Section Creator right away.

In addition to the Section Creator, Settle3 is also adding enhancements to the Ground Improvement feature with a new option for Stone Column Permeability. With this new option, stone columns will account for permeability with smear and well resistance effects.

Studies have shown that stone columns can be used for accelerating the consolidation rate of soft soil by providing a drainage path and reducing stresses in soil (Jie Han and Ye 2002). In Settle3, this option is introduced with an ‘allow drainage’ function. Users can determine the smear zone ratio of the columns to the diameter of the well, as well as undisturbed to smeared soil permeability. Once the allowed drainage option has been selected, the permeability of the stone columns is calculated based on the stress concentration ratio of the stone columns as well as the smear zone parameters from the dialog.

The above figure shows an example of how the introduction of stone column permeability results in an increase in consolidation settlement after one month of construction. As shown in the table, the time to reach a 90% degree of consolidation is shortened significantly when stone column permeability is introduced. The consolidation settlement with the drainage option also shows an increase after one month of embankment installation.

Multiple Load Importer

The new Multiple Load Importer feature works by allowing the exchange of boundary conditions between Settle3 and CSI SAFE. With this tool, the foundation geometry and stresses can now be directly imported into Settle3 from an excel file produced by CSI SAFE. In turn, Settle3 is able to export the moduli of subgrade reaction at each node of the foundation, which allows for a correct representation of the settlement in CSI SAFE.

Prior to this new feature, both structural and geotechnical engineers had to deal with a sometimes cumbersome and repetitive process of inputting load patterns and soil responses. With Settle3 specifically, this meant users had to manually import the load with the corresponding coordinates and magnitude of load. With the Multiple Load Importer tool, this process has been radically improved by allowing users to simply import batch loads with associated coordinates, magnitude, and elevation. Settle3 will then use this data to automatically generate query points either at the center of each imported load or at the edges of loads for output results such as subgrade soil modulus.

This innovative, new interface between these two software programs means not only time saved on the input of data, but also more accurate modelling for both geotechnical and structural engineers alike.

Rapid CPT Data Import

A new, Rapid CPT Data Import feature has been added that allows users to import multiple CPT data files from data forensics. After entering their login information from the database, users can import multiple CPT files from their cloud server and import the data into Settle3. This CPT data can be used to create boreholes and generate a soil profile for the model.

The new Rocscience Report Generator has also been added to Settle3. Formerly known as the Info Viewer, the Report Generator allows users to create sleek, professional looking reports with a customizable look and feel. Just like with the Info Viewer, the content of the report can be customized to include results such as settlement in the model, CPT analysis, liquefaction analysis, and ground improvement sensitivity analysis. Unlike before though, you can take those results further by adding images and comments for any additional details required.

Ground Improvement

Settle3- Ground Improvement with stone columns

For the Settle3 Ground Improvement feature, we’ve added two additional methods to improve a region of ground for settlement: Stone Columns and Vibro-Compaction.

Try the Stone Column option to improve any selected area of the region of ground for settlement. This ground improvement method can be applied in multi-layered soil. Users can control and define the stiffness, depth, spacing, and diameter of the stone columns, and Settle3 will use these parameters to re-calculate the settlement of the improved ground.

For sandy soils, users can apply the Vibro-Compaction technique. With this new feature, you can enter and adjust factors like the mean grain size, set your target relative density, and define the type of soil being vibro-compacted.

Once you’ve applied your ground improvement method, take things even further by using the Ground Improvement Sensitivity Analysis. This robust new feature allows you to analyze the impact on settlement and is a great way to get the most optimized and cost-effective analysis.

Embankment Designer

For users creating embankments, we now have added a new and more flexible approach to designing embankments in Settle3 with the Embankment Cross Section Designer. With easy-to-use drawing tools, you can use your mouse to add any shape or soil layers to an embankment cross-section. Add layers, multiple stages, and easily edit your vertices. When you’re done, just drag and drop the embankment across the ground surface and Settle3 will calculate the load of the embankment and the resulting settlement below.

Dry Ground Settlement

For users calculating settlement of dry sands during dynamic shaking, Settle3 has added a new Dry Ground Settlement feature. As many people know, severe shaking can cause liquefaction of saturated deposits, but for dry sand, this cannot occur. Depending on user input, Settle3 can now use two different methods – Standard Penetration Test (SPT) and Cone Penetration Test (CPT) – to calculate the settlement of dry sands during seismic shaking.

If the user selects the liquefaction method as SPT, Settle3 will follow the SPT Dry Sand Settlement method by relating the volumetric strain to the cyclic shear strain and earthquake magnitude (Pradel, 1998).

If the user selects CPT as the liquefaction method, Settle3 will follow the CPT Dry Sand Settlement method. This method is similar to the SPT method except it applies a correction factor to the standard penetration resistance (N1)60 based on the concept that soils with the same state parameter have the same response to loading (Robertson and Shao, 2009).
