摘　　要：为了研究并行管道阴极保护防干扰的最小间距,分别开展了现场测试、室内模拟试验及数值模拟,最终得出对于3PE涂层的并行敷设管道,在土壤电阻率为100Ω·m以下时,阴极保护系统防干扰的最小间距为4m的结论。To study the shortest distance of anti-interference of cathode protection for parallel pipeline,the site tests,indoor simulated tests and numerical simulation were performed. The conclusion was that if the soil resistivity was under 100Ω·m,the shortest distance of anti-interference for parallel pipeline with 3PE coating was 4m.
