Hydroconsolidation Properties
If you have added a hydroconsolidation region to the model, then you must define the hydroconsolidation material properties of the soil layers within the region.
To define hydroconsolidation material properties:
- Select Define Properties (Hydroconsolidation) from the Groundwater tab.
- You will see the Hydroconsolidation Properties dialog, which allows you to define a hydroconsolidation curve for each soil type.
- To define a hydroconsolidation curve for a soil type, select the Consider Hydroconsolidation checkbox, and enter data in the spreadsheet:
- By default, you can enter Pressure versus Delta Void Ratio to define a hydroconsolidation curve. Delta void ratio is the change in void ratio, and negative values indicate compression or collapse.
- Alternatively, if you select the Strain Based checkbox you can enter Pressure versus Strain (%) to define a hydroconsolidation curve. Strain is entered as a percentage. Negative values of strain indicate swelling and positive strain indicates compression or collapse. Note that the sign convention for strain is opposite to that used for delta void ratio.
- If you need assistance with the data values, you can select the Pick icon. You will see a dialog with published hydroconsolidation test results for a variety of soil types. Select a soil type and select OK, and the data will be displayed in the Hydroconsolidation Properties dialog. The data will be in the form originally published (Pressure vs. Delta Void Ratio or Pressure vs. Strain).
- You can also import a hydroconsolidation curve by selecting the Import button and importing an *.hfn file (hydroconsolidation function file).
- When you are finished defining hydroconsolidation properties, select OK to save your data and close the dialog.
As you enter data in the spreadsheet, the curve will be displayed in the plotting area at the right side of the dialog.
After hydroconsolidation properties have been defined, the properties are assigned to the soil layers of your model with the Soil Layers dialog.
- The soil types in the Hydroconsolidation Properties dialog are the same soil types which are defined in the Soil Properties dialog.
- The properties entered in the Soil Properties dialog are still applicable if you define Hydroconsolidation Properties. Hydroconsolidation properties are applied independently of the properties defined in the Soil Properties dialog, and are only applied within applicable hydroconsolidation regions, at the specified wetting stage.
