In　recent　years,　many　earthquake　disasters　have　shown　that　the　liquefaction　side　expansion　of　the　soil　in　the　inclined　liquefaction　site　will　increase　the　damage　degree　of　pile,　which　will　cause　the　failure　of　the　superstructure.　In　this　study,　an　efficient-finite　element　model　is　built　for　the　shaking　table　test　of　the　interaction　of　inclined　liquefied　site-pile　group-superstructure.　By　comparing　with　the　experimental　results,　the　rationality　of　the　model　building　method　is　proved.　Based　on　the　verified　method,　finite　element　models　of　typical　horizontal　and　inclined　liquefied　site-pile　group-superstructure　interactions　are　built.　Then,　the　dynamic　response　of　the　soil-pile　group-superstructure　system　under　different　non-liquefiable　crust　thicknesses　in　horizontal　and　inclined　liquefaction　sites　are　analyzed,　and　the　differences　between　the　systems　under　the　two　sites　are　discussed.　The　calculation　result　indicate　that　the　pore　pressure　ratio,　pile　displacement,　soil　displacement　and　pile　curvature　in　horizontal　and　inclined　sites　decrease　obviously　with　the　thickness　of　the　non-liquefiable　crust　increases.　Compared　with　the　horizontal　site,　the　attenuation　amplitude　of　the　inclined　site　is　more　obvious.　There　is　little　difference　in　pore　pressure　and　acceleration　of　soil　in　horizontal　and　inclined　liquefaction　sites　under　different　non-liquefiable　crust　thicknesses.　Compared　with　the　horizontal　site,　the　lateral　expansion　flow　in　the　inclined　site　produces　permanent　lateral　displacement,　which　increases　the　damage　degree　of　the　pile.
