• Abstract:
  Both open-ended and closed-ended pipe piles are often used in practice, but high-quality information available on the bearing capacity of these piles is very limited. The core of the present study was the pile load tests done on two pipe piles: one open-ended and the other closed-ended. The information generated by the load tests is particularly useful for engineers interested in the design of open-ended pipe piles in sand, as detailed data was collected on soil plug formation during driving and on static plug resistance. Better understanding of the load-carrying capacity of these piles can lead to significant cost savings. This appears to be especially true for open-ended piles. Both the driving response and static bearing capacity of open-ended piles are affected by the soil plug that forms inside the pile during pile driving. The formation of the soil plug and its effect on pile load response are still not completely understood. In order to investigate the effect of the soil plug on the static and dynamic response of an open-ended pile and the load capacity of pipe piles in general, field pile load tests were performed on instrumented open- and closed-ended piles driven into sand. The experimental data accumulated during pile driving and during the static load tests were then used to enhance understanding of the drivability and load capacity of both closed-ended and open-ended pipe piles.
