摘要In order to evaluate the reliability of the deck system of concrete bridge reasonably, multi-index multilevel reliability assessment model of the bridge deck system was set up based on the extension assessment method according to engineering diseases and related bridge maintenance assessment specification, and the classification standards of underlying assessment index were given as well. Correlation function and correlative degree in the extension set were introduced into. The subsystems' extension assessment analysis of the bridge deck system was conducted by the comprehensive correlative degree size. The multi-index multilevel extension assessment method was combined with the improved AHP, and the overall reliability level of the deck system was determined by calculating the correlation degree. The results show that reliability status of the bridge deck system is third class but close to forth class. Some effective treatments are taken according to the assessment results and the development of the diseases. The rationality and validity of the assessment results and treatment methods are verified by load test. In the process of the extension assessment, every subsystem extension assessment results are given, which is contributed to analyzing the causes of the reliability declining and making the reasonable decisions on maintenance and rehabilitation.
