Field and lab tests
SPT and CPT tests
Record a standard penetration test (SPT) by hand, and import cone penetration test (CPT) readings from a CSV file.
On this page
SPT
Open the borehole and choose the SPT tab. It says: "Standard penetration tests. N is the blows for the last two 150 mm increments."
- Press the add button.
- Record the blows of each 150 mm increment.
- Save.
The N value is worked out for you. A refusal shows as R.
CPT
Open the borehole and choose the CPT tab. It says: "Cone penetration test. One per borehole."
- Add the test details first.
- Import the readings from the CSV file of the cone rig.
The import takes up to 5,000 readings and 2 MB for each file. Readings at the same depth are replaced. The same file twice changes nothing. The tab draws a chart of the readings.
Who can add them
Drillers, engineers and admins, while the project is in Drilling. Engineers and admins can also change them in Testing and Review.
