In　order　to　help　engineers　to　better　learn　from　accidents　of　reinforced　concrete　structures,　accident　identification　and　processing　method,　this　article　introduced　the　ideas　of　CBR　to　the　accident　case　retrieval　methods　of　reinforced　concrete　structures.　At　the　same　time,　the　fuzzy　retrieval　and　knowledge　index　model　of　reinforced　concrete　structure　accidents　are　presented.　According　to　the　approximate　extent　of　construction　conditions,　the　approximation　of　construction　are　determined,　and　similar　cases　with　the　current　engineering　cases　then　retrieved　through　the　case　of　reinforced　concrete　structures,　which　the　designer　or　construction　workers　can　learn　from.
