Current Status Of Design And Construction Of Piles With A Pilot Hole On Rock, Charles C. Crowner Jan 2021

Current Status Of Design And Construction Of Piles With A Pilot Hole On Rock, Charles C. Crowner

College of Graduate Studies: Theses & Dissertations

Driven piles at project sites get their load bearing capacity from side friction along the driven lengths as well as from end resistance. Pilot holes is a pile driving assistance method used to aid driving displacement piles through hard/ dense layers and rock. These pilot holes can be a size smaller or larger than the pile that is to be installed. The pilot hole is first drilled down to a specific depth. The use of a pilot hole reduces the “end bearing” and “side resistance” within the drilled zone and aids the driving of the pile. This process also complicates …
