Abstract :
A field testing procedure was developed and the dynamic lateral response of eleven full-scale pipe piles was obtained experimentally. Steady-state vibration and plucking tests were conducted on piles embedded in both cohesive and granular soils at three separate sites. Two piles in cohesive soils were retested with either a conventional compacted granular soil or a cement-stabilized granular soil replacing the insitu surficial soil. Dynamic soil properties adjacent to the piles were determined by suitable field and laboratory testing techniques. The theoretical dynamic response was predicted using a two-degree-of-freedom analysis with stiffness and damping parameters obtained from the computer program, PILAY, developed by Novak and Aboul-Ella. The theoretical predictions for the dynamic response curves were compared with the observed field testing results.
