Driven Pile Capacity in Intermediate Geomaterial Formations
The natural variability of intermediate geomaterials (IGMs) exacerbates uncertainties in deep foundation design and may ultimately increase construction costs. There are well-established analytical methods for evaluating pile capacity and for predicting pile driving characteristics for cohesive soil, cohesionless soil, and rock. However, past experience indicates these methods may not be reliable for piles driven into IGMs, which often exhibit a wide array of properties with characteristics ranging from stiff or hard soil to soft weathered rock. Analytical results are compared to field capacities determined using PDA measurements obtained during pile driving and wave equation analyses conducted using the CAPWAP program. Capacity comparisons clearly demonstrate the inherent variability of pile resistance in IGMs and indicate that traditional semiempirical methods developed for soil may yield unreliable predictions for piles driven into IGM formations. The synthesis described herein has the potential to improve the reliability and cost effectiveness of deep foundations supported in IGMs by comparing design methods and material characteristic techniques with measured pile responses.
