During　the　1995　Osaka-Kobe　Earthquake,　different　degrees　of　damages　were　observed　in　Daikai,　Nagata,　Sannomiya,　Kamisawa　and　Shin-nagata　subway　station　and　running　tunnels.　Among　them,　the　earthquake　damages　at　Daikai　subway　station　were　the　most　serious.　It　is　the　first　large-scale　underground　structure　that　almost　collapsed　in　the　earthquake,　which　has　aroused　people＇s　concern　and　attention　to　the　seismic　issues　of　underground　structures.　A　large　number　of　theoretical,　numerical　and　experimental　studies　about　the　earthquake　damages　on　Daikai　subway　station　have　been　carried　out.　These　have　enhanced　the　comprehension　of　the　earthquake　damage　mechanism　and　the　failure　mode　of　underground　structures.　However,　most　researches　have　not　reached　a　consensus　so　far　regarding　the　damages　of　Daikai　subway　station　owing　to　that　their　conclusions　are　based　on　different　analysis　aspects,　diverse　collections　of　the　relevant　information　and　dissimilar　analysis　methods　and　models.　The　researches　on　earthquake　damages　at　Daikai　subway　station　are　reviewed.　The　effect　of　seismic　motion,　site　conditions　and　structural　characteristics　on　the　earthquake　damages　of　Daikai　subway　station　are　summarized.　Furthermore,　further　studies　on　the　in-depth　analysis　of　earthquake　damages　at　Daikai　subway　station　and　the　key　seismic　issues　of　the　underground　structures　are　proposed.　©　2018,　Editorial　Office　of　Chinese　Journal　of　Geotechnical　Engineering.　All　right　reserved.
