水利工程钢筋锈蚀检测应用研究

Study on application of corrosion detection to reinforcement of water works

以南湾灌区淮河渡槽钢筋锈蚀检测为例,探讨了钢筋锈蚀的评估方法及该方法的实用性,阐述了混凝土碳化和氯离子侵蚀机理及其影响因素,分析了各因素对混凝土损坏过程的影响。此外,概述了混凝土结构中钢筋锈蚀的机理和其他影响因素;提出了关于钢筋锈蚀的评估方法,评估了该工程钢筋锈蚀程度。

By taking the detection made on the reinforcement corrosion of Huaihe River crossing aqueduct in Nanwan Irrigation Dis- trict as the study ease, the the method for evaluating reinforcement corrosion and its practicability are discussed herein and the the mechanisms of concrete carbonization and chloride corrosion as well as their impacts are expatiated, and then the impacts from all the factors concerned on the damage process of concrete are also analyzed. Furthermore, the mechanism of the corrosion of the reinforcement in concrete structures as well as the other impacting factors are summarized, from which a method for evaluating reinforcement corrosion is proposed, whereafter, the corrosion degree of the reinforcement in the water works is evaluated with this method.
