Isolation　bearings　have　been　a　widely　applied　seismic　strengthening　technique　in　above　ground　structures.　Whereas,　the　sliding　isolation　bearings　were　seldom　used　in　underground　structures.　This　study　aims　to　explore　the　feasibility　of　sliding　isolation　bearings　reducing　the　seismic　response　of　underground　structures.　The　collapse　mechanism　of　underground　structures　was　firstly　analyzed　by　taking　the　Daikai　Station　as　an　example.　Numerical　results　demonstrated　that　the　collapse　of　the　structure　was　due　to　the　poor　ductility　of　the　intermediate　columns.　Therefore,　the　sliding　isolation　bearing　could　be　installed　between　the　columns　and　the　beam　to　reduce　the　lateral　deformations　of　columns.　In　order　to　determine　an　appropriate　coefficient　for　sliding　bearings,　static　analyses　for　the　capacity　of　columns　were　conducted.　Moreover,　the　performances　of　a　beam　bearing-column　system　were　also　investigated.　Finally,　seismic　responses　of　the　underground　structure　retrofitted　with　bearings　were　studied.　Numerical　results　presented　that　the　responses　of　both　columns　and　the　whole　structure　were　reduced　remarkably.　Moreover,　the　frictional　coefficient　of　bearing　influencing　the　seismic　responses　of　underground　structures　was　discussed.　And　some　interesting　conclusions　were　also　obtained　for　the　seismic　design　of　underground　structures.
