摘要

Pile lateral behavior is crucial in practice, particularly for the long-term performance of structures subjected to cyclic lateral loads. This study investigates the long-term lateral behavior of piles under creep and cyclic loading using power law models, via full-scale cyclic lateral load tests on six piles. Two power law models are introduced: one describes creep-induced strain accumulation with the creep exponent n, and the other captures cyclic loading effects with the cyclic exponent m, both exhibit significant log-log linearity. Findings indicate n stabilizes at 0.015 ± 0.003 across pile types, while m converges to 5.25, independent of pile types and the unloading percentage. Furthermore, combining the two models reveals that cyclic loading accelerates strain accumulation far more rapidly than creep. Current practices may underestimate cyclic-induced irrecoverable strains, highlighting the value of these models for pile design.
