摘　　要：接地和区域阴极保护技术分别从电气安全和防腐蚀安全两个方面来保证站场的安全运行。接地系统和站场内的埋地管线、储罐等电连接在一起,由于接地系统材料及表面状况与埋地管线、储罐等的差异,会对区域阴极保护系统产生较大影响,严重影响保护效果,增加设计难度。本工作系统地总结了国内外学者围绕接地系统对区域阴保影响进行的研究,同时介绍了相关的防护措施,并指出了该领域目前存在的问题及未来发展方向。Grounding and regional cathodic protection technology protect gas stations in term of electrical safety and anti-corrosion respectively.The common bonding of grounding grids to underground pipelines and storage tanks creates a big effect on the regional cathodic protection system due to the differences of materials and surface conditions between grounding system and buried pipelines or storage tanks,which can impact the protective effect and design difficulty.This paper summarizes domestic and overseas researches about the effect of grounding on regional cathodic protection system and introduces the related protective measures.The key problems are indicated and the development trend in this field is predicted.
