【摘要】 参照地铁工程结构服役环境,试验模拟了在杂散电流和氯盐溶液共同作用下,不同加载水平(0,0.2,0.4)对钢筋混凝土构件内钢筋锈蚀的影响。采用线性极化电阻法测量钢筋锈蚀电流密度,进行了定性分析和定量计算。试验结果表明:随着构件加载水平的增加,钢筋锈蚀电流密度也相应增加,建立了锈蚀时间与钢筋锈蚀量的定量关系。更多还原

【Abstract】 According to the service environment of subway structure,experiment is carried out to simulate influence of different loading level to reinforcement corrosion of R.C element under coupling of stray current and chlorine salt solution.The current density of the corrosion is measured with the linear polarization resistance method,the qualitative analysis and quantitative calculation is carried out.Experimental results show,with the increase of loading level,rebar corrosion current density also increases accordingly.The quantitative relations of the rust corrosion of reinforcement and the time are built.更多还原
