Plugging criterion for offshore pipe pile drivability

Abstract

Both plugged and coring behaviours are normally considered when analysing pile drivability. However, several authors challenge the idea that pipe piles can always plug. These views are argued partly on experience and engineering judgement, and partly on measured (although often proprietary) data. This paper proposes a new, objectively calculable criterion to determine whether a pile will plug during driving. The criterion is shown to agree with engineering judgement and be relevant to published data.
