Study Of Application Of Fuzzy Comprehensive Evaluation In The Quality Of Construction Bridge

In the bridge building items of basic construction, the quality is the project essential content. The project has the quality problem, can bring the serious consequence to the project, directly affects the bridge function, therefore has the necessity to make the synthesis appraisal to the bridge quality. Quality Evaluation generally consists of quantitative and qualitative factors. The former can be used test instruments and tools for the direct determination, strength, size, etc.; The latter is simply rely on the experience of testing and feel that no condensate will assess the accuracy of the results will be affected. The article applies the fuzzy synthetic evaluation method to the bridge quality research, and its aim is to ofer a new thought and a new method for the bridge quality research. At the same time, it is wandered to be able to set some referable values for the bridge quality research. Talking about the bridge quality research, some factors that need to beconsidered contain uncertainty (fuzzy). The appearance of fuzzy mathematics has ofered a set of efective method to describe this kind of thing whose boundary is not setled. Through establishing subordinate function and making these fuzzy factors quantifre. we can solve problems in fuzzy environment and make suitable decisions. Simultaneously combined with applying the method of Analytic Hierarchy Process (AHP), the weightiness of each appraised index is set, which can make the evaluation result more scientific and reasonable. The article through applying this fuzzy synthetic evaluation to HengShanDaQiao, we drew two conclusions: Firstly, HengShanDaQiao is reasonable; Secondly, the result of this evaluation system is credible, which has certain valuable feasibility and applicability.
