Abstract


With the increase of the age of the bridge in service in the growing volume of traffic and environmental loads , durability damage accumulated gradually affects the structural resistance , bridge strengthening and widening is an effective way to solve this problem and become in recent years the study of one of the hot issues Retrofitting structural durability study less . Analysis and evaluation of the durability of bridge strengthening and widening use of the reliability of the method and fuzzy evaluation method , and conducive to scientific management and conservation of the highway management department to continue serving on the bridge . First of all, the durability of concrete structures influencing factors , a lot of literature research , summarized the calculation model of carbonation of concrete and steel corrosion mechanism of each model . Consider the durability parameter measurement and calculation of randomness , reliability components and reinforcement of the old bridge reinforced sheet durability analysis, with reference to the relevant literature and combined with the actual bridge conditions , the target reliability values ??, carbonation and concrete cover cracking two limit state reliability . And predict the remaining life of the durability of components . Followed using fuzzy mathematical method for uncertainty factors influence the durability of widening , component durability , structure evaluation weight set and on the basis of membership functions , given the widening of old and new combination of structural durability evaluation model and calibration method using a ratio of 1 to 9 shows the recommended value the durability evaluation factors for each member of the right weight . Asymmetrical approach degree Rank . Finally, based on the above research results on a real bridge widening reinforced durability analysis and evaluation .
