Results of foundation engineering congress pile load tests

Results of axial load tests on an HP 14×73 pile, an 18-in.-diameter, closed-ended pipe pile, a drilled pier installed with the slurry method, and a drilled pier installed with temporary casing are presented. Each pile was tested two, five and forty-three weeks after installation. The fifty-ft-long piles were installed through twenty-three ft of dense sand overlying medium stiff clay. Measured axial load-pile head settlement and axial load distributions along the pile length, as well as calculated unit side resistance and corresponding dimensionless bearing capacity factors are presented for each of the load tests.
