Post-earthquake　investigations　have　shown　that　piles　in　liquefiable　soils　are　highly　susceptible　to　damage,　especially　in　sloping　sites.　This　study　examines　the　seismic　performance　of　pile　groups　with　lateral　spreading　through　advanced　numerical　modeling.　A　three-dimensional　finite　element　model,　validated　against　large-scale　shaking　table　test　results,　is　implemented　to　capture　the　key　mechanisms　driving　the　dynamic　response　of　pile　groups　under　both　inertial　and　kinematic　loading　conditions.　Parametric　seismic　response　analyses　are　conducted　to　compare　the　behavior　of　batter　and　vertical　piles　under　varying　ground　motion　intensities.　The　results　indicate　that　batter　piles　experience　increased　axial　compressive　and　tensile　forces　compared　to　vertical　piles,　up　to　70%　and　20%,　respectively.　However,　batter　piles　provide　enhanced　lateral　stiffness　and　shear　resistance　compared　to　vertical　piles,　reducing　horizontal　displacements　by　up　to　20%　and　tilting　the　cap　by　85%　under　strong　ground　motion.　The　results　demonstrate　that　batter　piles　not　only　enhance　the　overall　seismic　stability　of　the　structure　but　also　mitigate　the　risk　of　liquefaction-induced　lateral　spreading　in　the　near-field　through　pile-pinning　effects.　While　vertical　piles　are　more　commonly　used　in　practice,　the　distinct　advantages　of　batter　piles　for　seismic　stability　highlighted　in　this　study　may　encourage　using　more　advanced　numerical　modeling　in　engineering　projects.
