Research Of Concrete-Filled Steel Tube Arch Bridge Service State Evaluation Technology

Western transportation construction projects aimed at study and solve the long-span bridge monitoring, reinforcement, conservation of key technologies and the corresponding technical guidelines to be used in guiding our entire society are now the major concern of the long-span bridge monitoring, reinforcement, conservation work the launching.In concluding the long-span arch bridge security both at home and abroad on the basis of assessment, based on the theory of fuzzy comprehensive evaluation of long-span arch bridge state security service evaluation system with the existing norms related to information and evaluation system at all levels in the target vector, comprehensive assessment of the long-span arch bridge that the state security service assessment of the level of the assessment of each of the major grades.Concrete-filled Steel Tube arch bridge on service state, the structural model of assessment methods, ideas and steps. By AHP bridge will affect the working conditions of various factors structured, hierarchical, and the impact of a particular state or similar factors more closely together, form a layer, so as to establish a multi-level system of indicators, a solution Pipe concrete arch bridge service status are many factors that impact assessment to deal with difficult issues. To use fuzzy comprehensive evaluation of the pipe concrete arch bridge components respectively service condition assessment, the final assessment of the overall structure, and draw conclusions. According to the assessment model underlying factors affecting the membership function, in accordance with the second level of analysis to determine the factors underlying the right vector, and then identified two assessment of the factors affecting the weight vector, the last of the concrete-filled steel tube arch bridge service overall assessment of the state . By introducing explicitly based on the Analytic Hierarchy Process fuzzy assessment process, and methods. Through Visual studio 2005,Dreamweaver MX 2004,Microsoft SQL Server 2000 and other related software programming established a principle of the use of concrete-filled steel tube arch bridge assessment system, and an assessment of examples of judgement.
