摘要
为了解决地铁动态直流电流干扰对埋地管道的影响问题,通过对干扰源和干扰阴极保护附属设施的调查,并对管道阴极保护有效性和检查片质量损失(或电阻探头)的测试,研究了一套阴极保护有效性测试技术。地铁动态直流干扰下阴极保护有效性测试可以很好地反映在受地铁干扰状况下管段的阴极保护状况,对管道保护具有一定的指导作用。
In order to solve the problem of metro dynamic DC interference on buried pipeline, a set of effectiveness tests for cathodic protection were summarized through investigations of interference source and related auxiliary facilities, effectiveness tests of pipeline cathodic protection and quality loss check piece(or resistance probe). The tests could properly reflect cathodic protection condition under metro interference, which had significant effect on pipeline protection.
