In order to systematically expound the research situation of bridge design based on concept of life cycle cost（LCC） analysis,the research background,basic concept and principle of LCC analysis were introduced.The research status,the appropriate key technologies,and the prospects of LCC analysis for bridge design were illustrated.The study of basic theoretical system of LCC on board was summarized.The models of LCC and the study of framework were showed.The two most representative models were compared.The composition and calculation method of the bridge life cycle cost（BLCC） at home were introduced as well.LCC consists of per-unit cost of management,cost of users and social cost.The difficulties and obstacles encountered in calculation of the components were analyzed,and the existing problems in bridge design based on LCC were summarized.The study presented a necessary background for bridge design,maintenance,investment decision-making and the development of bridge management system based on LCC.
