摘要
根据钢筋混凝土结构构件的实际工作情况,提出了一种基于钢筋锈蚀劣化模型的混凝土结构使用寿命预测方法。该方法结合混凝土结构耐久性现状检测结果,以锈胀裂缝宽度或承载力达到极限状态作为结构使用寿命终结的控制标准,根据钢筋锈蚀量预测模型推算结构不同劣化程度时的剩余使用寿命。
According to the actual working condition of reinforced concrete structural member,and then a reinforcement corrosion deterioration model-based method for the prediction of the service-life of concrete structure is proposed herein.Combined with the detection result of structural durability state,the method takes the corrosion-induced crack width or the limit state of bearing capacity as the control standard of the end of the structure service-life and calculates the residual service-life of the structure for different deterioration degrees in accordance with the relevant reinforcement corrosion amount prediction model.
