Direct Shear

Supported Test Methods

Input

Lab-Strength/Consol | Direct Shear

To calculate the Direct Shear Values of a specimen, you must first select the standard from the Test Method field on the Direct_Shear table that the specimen is being tested against. Once selected, the necessary data entry fields will be automatically highlighted to assist you in entering the relevant data in the Direct_Shear_Stage table for the selected test method.

Enter the direct shear stage number data in the data entry fields on Direct_Shear_Stage (upper) table for each stage.

Enter the test data in the data entry fields on the on Direct_Shear_Stage (lower) table for each stage and when you change table or select save, the values will be calculated automatically and the result will be displayed in the calculated fields.

Enter the test data in the data entry fields on the on Direct_Shear_Consol table for each stage and when you change table or select save, the values will be calculated automatically and the result will be displayed in the calculated fields.

Direct Shear Results

To determine direct shear results from the direct shear plot, select Add-Ins > Datgel Lab and In Situ Tool > Direct Shear Graph to launch the compaction curve plot based on the recorded test data.

The initial plot displayed by the Datgel Lab and In Situ Tool is based on the test data entered into you gINT database and can be manually refined should it be necessary.

The Cohesion value can be set to zero by checking the Cohesion box.

If you are satisfied with the direct shear plot, click Ok and you will be returned to the gINT Input screen and if you move to the Direct Shear table, you will see that the Cohesion_Peak, Friction_Angle_Peak, Cohesion_Residual / Ultimate and Friction_Angle_Residual / Ultimate fields have been populated based on the direct shear graph.

If you are not satisfied with the defined compaction curve, click Cancel.

One-Dimensional Consolidation

Supported Test Methods

Input

Lab-Strength/Consol | Consolidation

To calculate the consolidation of a specimen, first you must enter the relevant data in the Consolidation table. 

Once the data is entered, click Save or Ctrl+S and green cells will be calculated.

Then you can move to the Consolidation_Increment and Consolidation_Readings.

Lab-Strength/Consol | Consolidation Increment

The Consolidation_Increment table (upper) stores the data of each increment. Enter the data for each increment (Increment Number and Stress or Mass). Relevant fields will be calculated at this point when you click Save, change row or Ctrl+S

Lab-Strength/Consol | Consolidation Readings

For each increment, enter data in the Consolidation_Readings table (lower). The Sequence_Number field is automatically populated and adjusted to the data. Enter Elapsed_Time, enter the first Clock_Time in dd/mm/yyyy hh:mm:ss and click Save for calculating the entire column. Enter the Gauge_Reading and Deformation (optional) and click Save or Ctrl+S to initiate the calculations.

Consolidation Results

To determine consolidation results from the consolidation plot, select Add-Ins > Datgel Lab and In Situ Tool > Consolidation Graph to launch the test curve plot based on the recorded test data. You must be on the Soil Consolidation related tables to run this command.

Load Deformation graph

Once the graph is launched, you can review the Load Deformation graphical data and set the calculation procedure (Akima, Cubic Spline or Approximative Spline) by clicking on the desired bullet in the lower frame of the graph as, shown in next set of figures.

Time Deformation increment graph

To launch the calculation for each increment, click on Time Deformation button.  Deformation vs. Time graph of all increments is displayed.

Each increment can be reviewed individually by clicking in the increment number from the list in the left side of the form.

The Y axis (Measured Deformation, Axial Strain or Void Ratio) can be selected for each increment graph by clicking on the desired bullet in the lower frame of the graph as shown in next set of figures..

After you have reviewed all increment graphs, click Ok and calculation results will be written to the related tables (Consolidation and Consolidation_Increment)

Output

• Graph Report | L S CONSOLIDATION 1 A4P
• Graph Report | L S CONSOLIDATION 2 A4P (Should be printed 1 specimen by run, due to a gINT limitation)
• Graph Report | L S CONSOLIDATION 3 A4P
