摘要：
In the existing concrete design method and construction standards, little about environmental affecting factors was taken into consideration. Based on the three-level-multi-index evaluating model, a method for evaluating durability of existing concrete bridges structures in marine environment was proposed in this paper, where durability factors and steel corrosion mechanism were analyzed. And the fuzzy membership degree of durability test indices at different levels is determined. Finally, this method is applied to Hangzhou Bay Bridge to verify it reasonable. The presented method has the advantages of simple form, explicit conception, evident levels and reference value to durability evaluation of bridges in other chlorine environment.
