Research Progress on Stray Current Interference on Buried Pipeline

With the continuous construction of my country’s subways and pipelines, the corrosion of pipelines caused by stray currents has attracted widespread attention. Due to the complex distribution of stray current and many influencing factors, the effective protection of buried pipeline has become a major problem in practical engineering. In order to better solve the problem of stray current interference to the buried pipeline, the classification of stray current, corrosion mechanism and interference index are introduced in detail. The current status and progress of research on the stray current distribution model and its source protection, the drainage measures of buried pipeline and its monitoring technology of domestic and foreign scholars are comprehensively discussed from the perspectives of subway and pipeline. It is clear that further improving the accurate simulation of stray current distribution model and developing new stray current monitoring technology are of great significance for the protection of buried pipelines. The future research directions of pipeline interference by stray current are prospected. The research results can provide a reference for researchers to carry out pipeline stray current interference research, and have important practical engineering significance.
