摘要

‏Anti-slide piles enhance slope stability under dynamic loading, reduce landslide susceptibility, and improve overall slope performance. This paper investigates the behavior of anti-slide piles through a series of instrumented, reduced-scale shaking table tests. Multiple pile-slope configurations were examined, varying pile spacing and diameter. The measured seismic amplification factors differed from values recommended for other structures, such as Mechanically Stabilized Earth Walls (MSEW). Consequently, a new bi-linear equation is proposed to calculate amplified acceleration as a function of base acceleration. Yield acceleration was quantified via pile deformation measurements and qualitatively assessed using digital image correlation (DIC) techniques applied to high-speed camera recordings. Results indicate an average yield acceleration of 0.33 g for pile-reinforced slopes. Both seismic amplification data and yield acceleration values were used to determine safe base accelerations for different pile-slope configurations. The stiffest configuration increased the safe base acceleration by 75%.‬‬‬‬
