Abstract: Soil creep is the process where soil deformation progressively increases under sustained loading. Under the coupled action of berth siltation soil and berth loads, soil creep occurs, impacting pile foundation bearing capacity. This paper investigates the creep characteristics of various soils, analyzes how soil strength and deformation affect pile foundation load response, and revises the p-y curve method for creep conditions. The results show that under the coupled action of bank slope siltation and creep, the long-term soil strength declines. The ε50 value, which is the strain at half the maximum principal stress difference in isochronous curves, gradually increases. The horizontal pile displacement becomes larger, yet with increasing time, the incremental horizontal displacement of the pile foundation becomes smaller and smaller.
