Analytical Methods to Predict Pile Capacities

A comprehensive test pile program was conducted for a large manufacturing facility. During this program, several pile types, including timber, precast concrete, concrete-filled pipe, and shells were driven and load tested to failure. Prior to load testing, the ultimate pile capacity was predicted by three static and two dynamic techniques. After testing, the predicted and measured capacities were compared. The wave equation and the Dutch cone penetration soundings resulted in the most consistent predictions.
