Abstract

Large PHC piles with a diameter of 1,000mm or larger were recently introduced for the first time in Korea. This paper presents full-scale static and dynamic pile load tests performed on two 1,000mm PHC piles and two composite piles with steel pipe piles of the same diameter in the upper portion, installed by driving and pre-boring. The objectives of the tests include evaluating pile drivability, load-settlement relation, allowable bearing capacity, and the stability of mechanical splicing element for the composite pile(a.k.a. non-welding joint). The performance of the large diameter PHC piles were thought to be satisfactory compared to that of middle sized PHC piles with a long history of successful applications in the domestic and foreign markets.
