摘　　要：文章分析了造成地网腐蚀和接地电阻偏高问题的原因,并尝试提出相应的解决措施。对于地网腐蚀,我们可以采取改变土壤环境、用覆盖层保护、选择合适的地网材料以及阴极保护等方法,以防止地网受到土壤腐蚀。对于接地电阻偏高,我们可以采用外引式接地,对土壤进行改良,深埋接地极,采用接地电阻降阻剂,以及扩大接地网尺寸,从而改善接地电阻。This paper analyzes the causes of the corrosion of the ground grid and the high grounding resistance, and tries to put forward the corresponding solutions. For the ground grid corrosion, we can change the soil environment, use the cover layer to protect, select the suitable ground grid material and cathodic protection and so on, in order to prevent the ground grid from being corroded by soil. For the high grounding resistance, we can use external grounding, improve the soil, deeply buried grounding electrode, use grounding resistance reducing agent, and expand the size of the grounding grid, so as to improve the grounding resistance.
