Comparative study of static loading test and statnamic on a steel pipe pile driven in a soft rock
T. Matsumoto, M. Tsuzuki & Y. Michi
Rapid load test, Statnamic, was carried out on an open-ended steel pipe pile driven in a diatomaceous mudstone. Dynamic testing and static loading test of the test pile was performed prior to the Statnamic test. Ground instrumentation was carried out aiming at measurements of the soil responsessuch as acceleration of the soil plug and excess pore water pressures during the Statnamic test. The load-settlement curve and axial force distributions of the test pile obtained in the Statnamic test. The load-settlement curve and axial force distributions of the test pile obtained in the Statnamic test were in good agreement with those from the static loading test until the Statnamic force attinaed to the ultimate bearing capacity, Pult, from the static loading test. The measured maximum Statnamic load was about 25% larger than Pult. However, static resistance after deduction of the velocity dependent components resulted 5.1 MN which was only 6% as large as Pult.
