Glossary

See Dynamic Load Test and Dynamic Pile Monitoring. Also referred to as PDA, but not the same as the equipment named Pile Driving Analyzer (PDA) used in dynamic pile monitoring and dynamic load testing.

A rigorous numerical evaluation of the dynamic monitoring data from an individual hammer blow to estimate static pile capacity, relative soil resistance distribution, pile stresses, and dynamic soil properties, using pile and soil models (more-comprehensive than dynamic method of analysis). Also referred to as wave matching. Performed with software such as CAPWAP and AllWave-DLT.

A mathematical equation that describes the mechanics of force transmission along an elastic rod (pile) that has been subjected to an impact from a mass having a specific initial velocity from which the motion and stress at any point along a pile being driven can be computed. Evaluates driving stresses and the relationship of capacity to blow count. Also referred to as wave equation analysis or wave equation program, and known by software names of TTI Program, MICROWAVE, GRLWEAP, AllWave-PDP, AllWave-VDP.

See Dynamic Load Test and Dynamic Pile Monitoring.

The recording of strain and acceleration induced in a pile during driving and presentation of the data in terms of stress and transferred energy in the pile, as well as of estimates of capacity, impact force, hammer rise, etc.

Evaluating pile resistance from impact-induced strain and acceleration in a pile during driving or restrike and typically with signal matching analysis.
