A New Analysis Of Data From Statnamic Tests On Piles In Clay

A series of pile load tests (maintained load tests, constant rate of penetration tests at different rates, and statnamic tests) was carried out on an instrumented model pile installed in clay beds prepared by consolidation of a slurry in a calibration chamber. The total load, shaft resistance and end bearing during the pile load tests were investigated. Following this, alternative methods of deriving the static load-settlement curve from a Statnamic test in clay taking into account damping effects have been proposed. These methods have then been used to interpret a statnamic test on a full size instrumented pile installed in a stiff glacial till.
