ESTIMATION OF LOAD CAPACITY OF PIPE PILES IN SAND BASED ON CONE PENETRATION TEST RESULTS

Pipe piles can be classified as either closed- or open-ended. In this paper, the load capacity of both closed- and open-ended piles is related to cone penetration resistance q-sub-c through an experimental program using calibration chamber model pile load tests and field pile load tests. A total of 36 calibration chamber pile load tests and 2 full-scale field pile load tests were analyzed. All the test piles were instrumented for separate measurement of each component of pile load capacity. Based on the test results, the normalized base resistance q-sub-b/q-sub-c was obtained as a function of relative density D-sub-R for closed-ended piles, and of both the relative density D-sub-R and the incremental filling ratio (IFR) for open-ended piles. A relationship between the IFR and the relative density D-sub-R is proposed as a function of the pile diameter and driving depth. The relationship between IFR and D-sub-R allows the estimation of IFR and thus of the pile load capacity of open-ended piles at the design stage, before pile driving operations.
