| 摘 要： | 氯化物是钢筋混凝土结构在使用寿命期内可能遇到的一种最危险的侵蚀介质,混凝土中钢筋表面的氯离子浓度超过一定的限值,钢筋就可能会发生锈蚀,锈蚀的钢筋会导致混凝土构件的承载力下降.通过分析国内外研究者所做的大量工作,讨论了氯离子侵入引起的锈蚀钢筋混凝土构件的抗力计算方法,为氯化物环境条件下混凝土结构的耐久性评估提供参考.

| Abstract: | Chloride is the most dangerous corrosion medium facing a reinforced concrete structure in its service life. Once the chloride ion concentration on reinforcement surface in concrete structure has exceeded a threshold value, the corrosion of reinforcement may occur, and the corroded reinforcement will bring about a decrease in bearing capacity of reinforced concrete component. In this paper, the calculation methods of resistance of reinforced concrete component influenced by chloride ion corrosion are discussed, which provides reference for the evaluation of durability of reinforced concrete structure in the chloride environment. |
