Pile Dynamic Analyzer Test Wave Equation Analysis For Pile Driving

The pile dynamic analyzer technology is the most prevalent system for dynamic load testing and pile driving monitoring. The high-strain dynamic load tests, referred to as PDA tests, assess the capacity, integrity, and driving stresses during the installation of driven piles. Further monitoring of hammer energy and efficiency can be made during driving. All testing procedures follow American Society for Testing and Materials International D4945 Standard Test Method for High-Strain Dynamic Testing of Deep Foundations.

Pile dynamic analyer tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer. Re-strike PDA tests are often recommended; if the driving hammer is no longer on location, a drop weight may be used to impact the pile.

Engineers can perform this work on both test and production piles using the high-strain impact provided by either an impact hammer or a drop weight. Piles can be steel, concrete, or timber with sensors temporarily attached to the pile which allow for monitoring during driving and collecting data real time. The real-time collection of data allows for more efficient field direction during pile installation.

High Strain Dynamic Pile Testing Advantages

• Applicable both Offshore & Onshore for Bored, Driven Concrete, Steel, Timber Piles
• Generates Useful Information other than pile capacity
• More tests can be conducted & hence Better Quality Assurance
• Requires Less space compared to Static Tests
• More Safety Compared to Static Testing
• Evaluates Pile Integrity Incl. Extent & Location of Damage
• Determines if Problem is Pile, Soil or Hammer
• Confirms Capacity, Even at Large Loads
