Key bridge as a road traffic junction control parts, it is subject to the design standards, the intricate interaction of the useful life of engineering materials, external environment, conservation quality, traffic loads role, contingencies and other factors, is bound to make a bridge structure internal mutation, leading gradually reduced carrying capacity, plus bridge corrosion, aging, fatigue, breakage of potential problems to the normal use of the bridge. Bridge repair and reinforcement of research in this paper computer system for bridge management department in the bridge of the Maintenance decisions are often based on the experience of qualitative understanding and engineers to bridge situation to the lack of scientific guiding ideology, the ills of the detection system evaluation method bridge database and reasonable bridge evaluation subsystem, collected the bridge typical form of the disease and its mechanism, and access to expert knowledge in specialized areas, the use of expert knowledge to model expert behavior, to make appropriate repair and reinforcement program. Text is divided into seven chapters: The first chapter is the introduction, summarize and generalize the bridge repair and reinforcement of the basic concepts of computer systems, according to the practice experience in domestic and international bridge management system, a review of the development history and current situation of the Bridge Management System to determine the research direction and guiding ideology of this article; Chapter II data management subsystem, collect bridge design, construction records and data of the test data, and bridge inspection data, including data obtained through routine checks and key parts of the examination. This subsystem is the foundation of the whole system; evaluation subsystem, three individual indicators and indicators proposed for the evaluation of the bridge technical condition, and to develop appropriate evaluation criteria; Chapter is a decision-making system, including diseases of the reasons analysis as well as maintenance and repair of decision-making, the establishment of a decision tree model of the bridge and Treatment Measures expert database; Chapter bridge repair and reinforcement of computer system applications, a major step in the practical application and data statistical processing and two bridges as an example to illustrate the application process; Chapter VI is a software system analysis and structural design, system software design process, the basic structure and function; Chapter VII Conclusion and Outlook, review this article arguments and the results of the work, the inadequacies of the existing and future direction point of view.
