Three　experimental　structural　models　of　a　small　radius　curved　bridge,　which　include　a　three-span　small　radius　curved　bridge　model　and　its　corresponding　two　different　simplified　models　that　are　widely　used　(e.g.,　one　mass　simplified　model　and　one　single　pier　simplified　model),　will　be　constructed,　and　then　three　bridge　structure-foundation　soil　system　models　will　be　designed　to　carry　out　shaking　table　tests.　From　the　shaking　table　tests　on　the　three　models　under　different　input　motions,　the　dynamic　soil-structure　interaction　effects　on　the　dynamic　characteristics,　seismic　response　rules,　and　damage　modes　of　the　three　models　will　be　studied　and　compared.　Before　the　test,　the　measured　fundamental　frequency　of　the　single　pier　simplified　model　was　minimum　and　that　of　the　mass　simplified　model　was　maximum　in　the　three　test　models.　In　the　test,　with　an　increase　in　the　input　motion　peak　ground　acceleration　(PGA),　the　soil　disturbance　and　deformation　increased　gradually,　and　the　foundation　soil　separated　gradually　from　the　model　structures,　and　local　damage　to　the　structures　occurred,　and　the　fundamental　frequency　of　the　curved　bridge　model　structure　decreased　most　significantly　in　the　three　models.　The　test　phenomena　and　measured　results　indicate　that　the　single　pier　simplified　model　could　be　used　to　approximately　simulate　the　acceleration　and　displacement　responses　of　the　fixed　pier　and　corresponding　pile　of　the　curved　bridge,　and　the　single　pier　simplified　model　could　be　used　to　approximately　simulate　the　strain　response　of　the　fixed　pier　and　corresponding　pile.　The　mass　simplified　model　was　not　suitable　to　simulate　the　acceleration,　displacement,　and　strain　responses　of　the　fixed　pier　and　corresponding　pile.　It　is　not　appropriate　to　use　the　mass　simplified　model　and　the　single　pier　simplified　model　to　simulate　the　pile-soil　contact　pressure　of　the　fixed　pier　model.　In　addition,　the　single　pier　simplified　model　could　not　reflect　the　torsion　characteristics　of　a　curved　bridge.
