What is the relationship between qc and qd?

qc is cone resistance measured with the Cone Penetration Test (CPT) where a cone is pushed into the ground at a constant speed (e.g. 2cm/second). It’s also know as the static cone penetration test. qd is cone resistance but measured dynamically and is known as the...

Is a continuous measurement of force and penetration is made?

Yes, the force and penetration is measured with each blow. This continuous measurement is what the user sees on the Dialogue Terminal and on the software: it is the penetrogram. The user can also check the data table on the dialog terminal or through the software....

Does the PANDA® account for any dynamic effects in the test results?

The dynamic effects have not been considered for the PANDA®. Nevertheless, these effects are reduced to a minimum as the speed of deformation is very low. The advantage of the PANDA® sounding (compared to pile driving) is that you can reduce the hammering speed (and...
