Structural Failure of Pile Foundations during Installation
Working stresses in piles under service conditions are generally limited by codes to assure safety against failure. Pile structural failures under working conditions are relatively rare. Driven piles, however, are subject to structural failure during the installation process. Under each hammer impact, a pile is subjected to a complex combination of compressive, tensile, torsional, and bending forces. These dynamic driving forces will probably be the highest the pile will ever experience and may produce stresses that exceed the pile material strength. Damage may occur at the pile head, toe, or along the shaft. This paper presents discussions of the dynamics of hammer-pile-soil interaction, the mechanics of pile driving stresses, field instrumentation and testing to monitor pile driving stresses and structural integrity, and examples of the detection of driving induced pile damage.
