摘　　要：利用CDEGS软件计算了两个相临接地网共存时其中一个接地网的部分参数,分析了两个相临接地网间的影响。得出了两个相临接地网间的影响与接地网周围土壤模型、两个接地网的相对面积大小、两个相临接地网相临导体的间距等因素有关,但一般情况下对接电网参数的影响不会大于10%的结论。This paper calculates part of the parameters of one of the two adjacent grounding grids with the CDEGS software, analyses the influence of these grids and works out that the influence of these grids is relevant to the factors including surrounding soil model of the grounding grids, the relative areas of these grids and the distance between the adjacent conductors of these grids. But generally speaking, the influence on grounding grid parameters should not be greater than 10%.
