The　rocking　bridge　has　attracted　a　significant　research　interest,　due　to　its　excellent　self-centering　capacity　after　the　severe　earthquake.　However,　the　vast　majority　of　previous　studies　on　the　seismic　behavior　of　rocking　bents　were　usually　conducted　based　on　the　assumption　of　the　rigid　bedrock　without　considering　of　soil-structure　interaction　(SSI).　Hence,　this　paper　investigates　the　seismic　performance　of　the　self-centering　rocking　bent　considering　the　SSI　effect.　Focusing　on　the　double-column　self-centering　rocking　bent　equipped　with　and　without　angle　steels　(SCRB-A　and　SCRB)　and　the　conventional　double-column　reinforced　concrete　bent　(RCB),　the　high-fidelity　finite　element　models　considering　the　SSI　effect　are　established.　The　seismic　responses　of　the　bents　with　fixed-base　(without　SSI)　and　flexible-base　(with　SSI)　are　comparatively　evaluated.　The　influence　of　the　shear　wave　velocity　of　soil　on　the　seismic　behavior　of　the　bents　with　the　SSI　is　also　discussed.　The　results　show　that　the　SSI　has　significantly　effect　on　the　seismic　responses　of　the　three　bents.　The　displacement　responses　are　generally　increased　when　the　SSI　is　considered,　and　the　amplifications　of　the　seismic　responses　of　the　SCRB-A　and　SCRB　considering　SSI　are　more　obvious　than　those　of　the　RCB.　With　the　increase　of　the　shear　wave　velocity,　the　in-fluence　of　the　SSI　on　the　displacement　responses　of　the　RCB　becomes　progressively　less　sensitive,　however,　the　totally　different　trends　can　be　found　in　the　SCRB-A　and　SCRB　with　SSI.　Moreover,　SCRB-A　exhibits　better　seismic　performance　when　compared　with　the　SCRB　and　RCB　for　the　cases　with　or　without　the　SSI　effect.
