PDA, SPECS, SPTCan the Pile Driving Analyzer (PDA) be used to measure the energy transferred to an SPT rod?
The Pile Driving Analyzer may be used to measure the energy transferred to Standard Penetration Tests (SPT) rods by SPT hammers, as called for by the many project specifications that mandate compliance with the American Society of Testing and Materials Standards American Society for Testing and Materials (ASTM) D4633 and ASTM D6066, or with the European Standard EN ISO 22476-3. Both the European Standard and ASTM D4633 accept only one way of determining this energy – through Force and Velocity measurements on the rod. This is something that the PDA can do, provided that the sampling frequency requirements of the code applicable in your part of the world (ASTM D4633 or EN ISO 22476-3) is met. The PDA model PAK fully complies with the analog system requirements of ASTM D4633-05 when samples are taken at 20 kHz. It should be noted, however, that in soils with low N values (easy driving), sampling at 20 kHz may result in too short a total sample time. An add-on SPT Software Program is avai
