In　this　paper，the　constitutive　parameters　are　determined　based　on　the　triaxial　test　data，and　the　finite　element　model　of　the　field　test　and　the　centrifuge　test　is　established.　The　applicability　of　the　SANISAND　constitutive　model　to　pile-soil　interaction　under　static，seismic，and　cyclic　loads　is　investigated　in　order　to　provide　a　reference　for　its　engineering　design　application.　The　results　indicate　that　the　SANISAND　constitutive　model　can　well　reproduce　the　pile　top　load-displacement　characteristics　of　different　pile　diameters　under　horizontal　static　loads，the　variation　trend　of　acceleration　and　pore　pressure　time　history　curves　under　earthquakes，and　the　pile　deformation　performance　under　short-term　cyclic　horizontal　loads.　However，it　is　not　possible　to　accurately　reproduce　the　negative　peak　pore　pressure　caused　by　dilatation　as　well　as　the　cumulative　deformation　under　long-term　cyclic　loads.　©　2024　Science　Press.　All　rights　reserved.
