CFI's Driven Pile Academy: Hosted by the PDCA

Soil Resistance and Blow Count

May be correlated through multiple means Energy Formula (Dynamic Formula) ◦ Based on an assumption of the energy generated by the hammer vs energy dissipated into the soil. Wave Equation Analysis ◦ Models the hammer-pile like an elastic rod and models both High Strain Dynamic Testing ◦ Measurement and analysis of stress wave to calculate static resistance Static Load Testing ◦ Measurements can be correlated to driving resistance
