To determine rational design parameters for piles at a bridge abutment site, two test piles (356x368x174 kg/m steel H-piles) of 50.7 m and 40.4 m long were installed. The two piles were driven into completely weathered meta-siltstone. They were instrumented with an inclinometer access tube and vibrating wire strain gauges on the shaft to monitor the deflection profiles and load transfer of the piles during pile driving and load testing. Dynamic load tests at end-of-pile-installation and at re-strike and static load tests were carried out on the piles. In this paper, details of the instruments installed, the testing arrangements and procedures, and their results are described. A discussion of the dynamic and static pile load test results, and a comparison of the Hiley, CAPWAP/CASE and static capacities are given.
