Pile Driving Analyzer (PDA) Model 8G
Standard: ASTM D4945
System for dynamic load testing and pile driving monitoring
Bearing capacity of all types of deep foundations
The Pile Driving Analyzer (PDA) eighth generation (8G) system acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D4945) may be performed. The tests require the impact of a pile driving hammer or, if that is not available, of a suitable drop weight.
High Strain Dynamic Load Test with the PDA-8G
The PDA-8G assesses bearing capacity and structural integrity. Preliminary field results are further analyzed with the CAPWAP® software, for results that correlate very well with static load tests. High Strain Dynamic Load Tests may be performed on drilled shafts, continuous flight auger, cast-in-situ or driven piles. The PDA-8G has new features that make it easier to use for drilled shaft testing, such as the option of conducting the test with four or more wireless strain transducers. When a ram of sufficient mass is used, high strain dynamic load tests performed with the PDA may meet Rapid Load Test standards (ASTM D7383).
