钢筋混凝土结构氯离子侵蚀耐久性寿命预测

Durable life prediction of reinforced concrete structure under chloride penetration

根据Fick第二扩散定律和可靠度理论,建立耐久可靠指标和侵蚀时间之间的关系,指出当耐久可靠性低于规定可靠指标时,钢筋混凝土结构到达其氯离子侵蚀耐久性寿命。

Based on the basis of the second Fick＇s law and the reliability theory, the relationship between the durable reliability index and the corrosion time is established. It points out when the durable reliability index falls below a stipulated index, that the reinforced concrete struc-ture has reached its durable life.
