摘要
环境作用谱在混凝土耐久性研究领域的应用尚不多见.环境作用谱应用于混凝土耐久性上,已取得了部分研究成果,在此基础上,分析其存在的缺陷.提出了在一定的环境作用谱作用下,采用绝缘电阻法、腐蚀电流法和损伤变量法,研究钢筋混凝土结构腐蚀当量加速关系的建议.明确了环境作用谱理论,在加速腐蚀方面的应用方向.为混凝土耐久性研究提供新的理论方法.
Though application of environmental action spectrum in concrete durability study is still rare,some results have been achieved by now.Based on that,this paper analyzes the deficiency of them and proposes advices on studying reinforced concrete corrosion equivalent accelerated relationship using the methods of insulation resistance,corrosion current and damage variable method in certain environmental effect spectrum.The advices clarify the environmental effect spectrum theory in the direction of the application of accelerated corrosion of reinforced concrete structures,which provides new method for the study of the durability of concrete.
