摘　　要：根据混凝土结构耐久性包含众多未确知性的特点,选择最能影响结构耐久性的因素作为评估指标,定义了指标未确知测度以及指标对确定构件耐久性等级所起作用大小的指标分类权重,建立了构件耐久性未确知综合评估系统;采用层次分析法,计算各构件对整体结构耐久性的重要性权重。建立了未确知综合评估系统与AHP相结合的混凝土结构耐久性评估模型。应用实例表明,所建模型的正确性和适用性。It is well-known that many unascertained factors determine the durability of concrete structures.In this paper,we choose main influencing factor as evaluation index,define new concepts of index unascertained measure and weight of index classification which presents the index＇s contribution to samples classification,and establish a unascertained synthetical evaluation system.Making use of this system and the analytic hierarchical process,a new evaluation model for the durability of concrete structure is established.The correction and adjustment of the model are identified by a real example.
