Using the finite element method, this study investigates the seismic behavior of hunchbacked block-type gravity quay walls with varying configurations. The research employs adaptive meshing strategies and error-based adaptivity techniques to refine the plane strain FE meshes. Interface elements are utilized to simulate discontinuities along the wall height, particularly between concrete blocks, and to model the interaction between the quay wall and the adjacent soil medium. The developed FE models are validated against data from 1g shaking table tests available in the literature. The study evaluates the seismic performance of three quay wall models, each with a unique configuration, under a range of seismic loads, including peak ground accelerations from 0.1g to 0.9g and frequencies from 3.0 Hz to 9.0 Hz. The findings indicate that increasing hunch height and optimizing the upper inclination angle effectively reduce lateral earth pressures and horizontaldisplacements, enhancing seismic performance. The study recommends positioning critical structures, infrastructure, and sensitive buildings in the backfill area at a distance greater than the wall height, as maximum backfill settlement occurs between 0.55H and 0.65H from the quay wall, where significant settlement poses risks to facilities. Additionally, acceleration amplification in the backfill decreases at distances greater than the wall height, indicating reduced seismic impact.
