To　evaluate　the　beneficial　effect　of　rubber　bearings　on　the　seismic　performance　of　underground　station　structures,　three-dimensional　finite　element　models　of　seismic　soil-structural　systems　are　established　for　a　single-layer　double　span　subway　station.　The　seismic　mitigation　effect　is　investigated　by　employing　the　pushover　analysis　method.　The　obtained　results　indicated　that　the　installation　of　rubber　bearings　can　effectively　alleviate　stress　concentration　and　damage　degree　of　the　central　column,　especially　at　its　end　area.　Compared　with　the　conventional　column,　the　elastic　and　elastoplastic　deformation　capacity　of　the　column　fitted　with　rubber　bearings　both　improved　significantly.　It　was　also　found　that　the　load　bearing　and　deformation　performance　decrease　with　the　increase　of　the　axial　pressure　ratio.　Furthermore,　the　lateral　force　distribution　mechanism　of　the　structural　system　fitted　with　the　rubber　bearings　is　significantly　different　from　the　original　structure;　the　deformation　and　internal　forces　of　central　column　of　the　seismic　mitigation　structure　decreased　substantially,　but　side　walls＇　deformation　and　internal　forces　increased　slightly.　The　proportion　of　shear　force　taken　by　the　central　column　has　decreased,　while　the　side　walls　have　taken　larger　share,　i.e.,　the　rubber　bearings　facilitated　the　transfer　of　seismic　forces　from　the　middle　column　to　the　side　wall.
