摘　　要：氯离子在自然环境下是影响钢筋混凝土寿命最重要的因素。环境中含量较多的氯离子会破坏混凝土内部钢筋,导致钢筋被侵蚀及混凝土被破坏,氯离子是钢筋混凝土结构被提前腐蚀的重要原因,本文研究时间、温度、氯离子浓度等因素对氯离子侵蚀混凝土速度的影响,对保护混凝土寿命的意义重大。Chlorine ion is the most important factor affecting the life span of reinforced concrete in the natural environment. Environmental content of chloride will damage concrete internal steel, lead to reinforcement erosion and concrete damage. Chloride is the important reason of reinforced concrete structure corrosion in advance. Time, temperature, chloride concentration on the influence of chloride erosion concrete speed are studied, which is of great significance to the protection of concrete life.

关 键 词：钢筋混凝土 侵蚀 氯离子 COMSOL
