摘　　要：基于等值土壤电阻率的概念 ,以已提出的两层土壤中正方形接地网的接地电阻公式为基本数学模型 ,导出了两层土壤中任意形状接地网的接地电阻解析公式 ,与计算机数值算法比较 ,所提出的新公式的计算误差通常小于 10 %。Based on the derived Formula for grounding resistance of a square grid in two layer soil and the concept of equivalent soil resistivity, an analytic formula to estimate grounding resistance of grid with any shape in two layer soil is derived Comparing the calculation results from the new formula with those from numerical calculation, the error from the formula proposed will be less than 10% generally \ \
