摘　　要：镜像法是一种计算不均匀土壤接地电阻的求解方法,本文用该方法求出双层土壤的接地电阻,并与均匀土壤的接地电阻进行了比较,推出了上下两层土壤电阻率的不同对接地电阻的影响曲线,为工程应用提供了参考。Image method is used for calculating ground resistance in two-layer soils. The paper presents grounding calculation based on this method, and compares the results with that in uniform soil. We gain the grounding resistance curve affected by the differences of two layers soil resistivity. It can be available for reference in engineering application.
