摘　　要：在沿海或使用除冰盐地区,氯离子是引起混凝土结构中钢筋锈蚀,进而导致结构破坏的主要原因,科学准确地描述氯离子侵入混凝土的过程,对于已有混凝土结构的寿命预测和新建结构的耐久性设计均具有重要的意义。目前,描述氯离子侵入混凝土的模型主要是Fick第二定律模型,该模型不能考虑各参数的随机性,可靠性模型则能够考虑模型中各参数的随机性,可以更科学全面的描述氯离子侵入混凝土的过程。At marine or de-icing salt environments, the chloride ion is the main reason that leads to reinforcement corrosion and causes the damage of the concrete structure, therefore, it is very significant for life prediction of existing concrete structures and durability design of new structure to scientifically and accurately describe the process of chloride ion invading in concrete. At present, the model describing chloride ion invading in concrete is mainly Fick second law model that can not consider randomicity of parameters, however, reliability model can consider randomicity of parameters and more scientifically and comprehensively describe the process of chloride ion invading in concrete.
