To　protect　museum　cultural　relics,　seismic　damage　causes　as　well　as　aseismic　strengthening　methods　of　free-standing　museum　cultural　relics　were　studied　in　this　paper.　Museums,　cultural　relics　and　their　bases　were　all　considered　to　study　causes　of　damage　of　free-standing　relics.　Shortages　of　typical　domestic　aseismic　methods　were　discussed,　overseas　isolation　techniques　were　introduced.　Based　on　2　typical　examples,　reasonable　strengthening　methods　for　museum　cultural　relics　were　further　demonstrated.　Results　show　that　main　damage　causes　of　museum　cultural　relics　under　earthquakes　relate　closely　to　over　strong　earthquake　intensity,　shortage　of　strengthening　measures　of　relic,　destruction　of　showcase　or　museum　building　and　so　on;　museum,　showcase　and　relic　are　all　important　factors　for　aseismic　strengthening　of　the　relics.　Besides,　to　effectively　protect　the　relics,　traditional　strengthening　methods　have　to　be　improved;　development　as　well　as　application　of　new　isolation　devices　is　encouraged.
