A　boundary　forced　response　displacement　method　is　proposed　for　the　seismic　analysis　of　symmetrical　underground　structures　based　on　the　requirement　of　quasi-static　pushover　test　of　soil-underground　structure　systems.　The　implementation　procedure　and　special　features　of　the　method　are　introduced　in　detail.　We　took　the　Daikai　subway　station　which　was　damaged　during　the　Kobe　earthquake　in　Japan　as　an　example　for　the　analysis,　and　compared　the　results　of　boundary　forced　response　displacement　method,　the　FEM　seismic　deformation　method　and　the　dynamic　time-history　analysis　method.　The　results　show　that　the　accuracy　of　the　new　method　was　much　higher　than　the　FEM　seismic　deformation　method　when　the　width　of　the　model　was　reasonable.　The　errors　of　the　internal　forces　and　the　story　drift　were　less　than　15%.　The　new　method　is　an　effective　simplified　method　for　seismic　response　analysis　of　symmetrical　underground　structures.　The　attenuation　law　of　lateral　boundary　forced　displacement　was　analyzed.　It　provides　references　for　the　quasi-static　pushover　test　of　soil-underground　structure　system.　Copyright　©2021　Engineering　Mechanics.　All　rights　reserved.
