The　rupture　of　soil　layer　on　bedrock　may　be　induced　by　earthquake　fault　dislocation　of　bedrock　when　earthquake　occurs,　and　it　will　directly　lead　to　destruction　of　engineering　structures　upon　the　fault,　especially　the　underground　structures.　The　study　on　this　problem　has　been　attracting　more　attention　in　recent　years.　Previous　research　results　and　progresses　in　the　field　have　been　analysed,　and　the　rupture　modes　have　been　summarized.　Some　existing　problems　and　research　tendencies　are　analyzed.　Some　research　results　show　that　the　fault　type,　fault　location　quantity　and　direction,　the　depth　and　physical　properties　of　overlaying　soil　layer　are　the　main　factors　affecting　the　rupture　processing　of　soil　layer　overlaying　on　the　dislocated　bedrock,　and　also　indicate　that　the　reverse　fault　induced　rupture　grader　of　soil　layers　is　the　strongest,　and　the　normal　fault＇s　rupture　is　moderate　and　the　strike-slip　fault＇s　rupture　is　the　weakest.
