During　the　Kobe　earthquake　in　1995,　Daikai　subway　station　suffered　the　severe　collapse,　which　aroused　people＇s　more　attention　to　the　earthquake　damage　response　of　underground　structures.　In　order　to　investigate　the　seismic　failure　mechanism　of　underground　frame　structures,　a　series　of　1/50-scaled　dynamic　centrifuge　tests　were　conducted.　To　make　the　underground　structures　produce　a　reasonable　seismic　failure　mode　in　tests,　an　experi-mental　scheme　was　designed　in　detail　based　on　the　author＇s　previous　numerical　studies.　With　the　purpose　of　simulating　the　vertical　inertial　effect　of　the　overburden　soil　in　the　dynamic　centrifuge　tests,　a　certain　proportion　of　steel　grits　were　mixed　into　the　overlying　soil.　A　model　structure　finally　occurred　the　overall　collapse　mode,　which　was　similar　to　that　of　Daikai　subway　station.　Based　dynamic　centrifuge　tests,　the　seismic　failure　mecha-nism　of　shallow　buried　underground　frame　structure　was　analyzed　and　summarized　in　the　paper.　It　could　offer　a　reference　for　the　cause　of　collapse　of　Daikai　subway　station.　The　series　of　tests　provided　valuable　experimental　data　for　further　studies　of　the　earthquake　damage　response　of　underground　frame　structures,　and　also　enriched　the　testing　technique　for　destructive　model　tests.
