| Abstract: | Based on the durability failure characters, the key factors that affect the bridge structure durability are analysed. The durability design plan evaluation model is setup and the relation between design plan and factors is discussed. The fuzzy evaluation method is used to evaluate the durability design of bridge structure, and the durability design grade of bridge structure is decided, which is very useful for maintenance and management of bridge structure under marine environment. |
