Abstract

This study developed a numerical method for evaluating ground movements while a pile is being driven and obtained a comprehensive load-displacement curve for a driven pile. The tested pile exhibited a larger scale than those tested in previous studies, and was penetrated into a considerable depth of the stratum. Numerical results revealed that both the ground movement and residual force caused by the pile driving was able to be analyzed using the proposed numerical procedure. Although the load applied to the tested piles differed from that determined by numerically analyzing incremental pile displacement, the load-displacement behavior of the piles calculated using the proposed method was consistent with that measured in pile-load tests before the piles were stressed to their peak loads. This study presents a series of helpful figures to support the design of driven precast concrete piles based on the results of numerical studies and field tests.
