摘　　要：为讨论钢筋混凝土中电化学保护技术对钢筋腐蚀的防治,采用理论结合实践的方法,立足电化学保护技术的原理,分析钢筋腐蚀防治中常用的电化学保护技术,并结合实际案例,分析了此种钢筋腐蚀防治技术的实际应用。分析结果表明,电化学保护技术可通过在钢筋表面施加电流,改变钢筋的电位,使其成为阴极,从而减缓或阻止腐蚀的发生,实现对钢筋混凝土结构中钢筋腐蚀的有效防止。In order to discuss the prevention and control of steel corrosion by electrochemical protection technology in reinforced concrete,a method combining theory with practice is adopted.Based on the principle of electrochemical protection technology,the commonly used electrochemical protection technology in steel corrosion prevention and control is analyzed.Combined with practical cases,the actual application of this steel corrosion prevention and control technology is analyzed.The analysis results indicate that electrochemical protection technology can effectively prevent corrosion of steel bars in reinforced concrete structures by applying current on the surface of the steel bars,changing their potential to become cathodes,thereby slowing down or preventing corrosion.
