A Case History of Pile Relaxation in Recent Alluvium
This paper describes a case history where penetration resistance of closed-end pipe piles in sand decreased with time. Pore pressure measurements from cone penetration tests (CPTu) suggests that the sand exhibited dilative behavior during the test, and the dilative soil behavior may have contributed to a temporary increase in penetration resistance during initial driving. A lower penetration resistance observed during re-strike was attributed to re-equilibrium of hydrostatic pressure. Static pile capacity analysis and dynamic pile driving analysis with PDA data indicate that pore pressure measured during CPTu is an appropriate tool for predicting pile relaxation.
