摘要
基于等值土壤电阻率的概念和已提出的双层土壤中单根接地棒接地电阻的解析公式,导出了双层土壤中N根组合接地棒接地电阻的解析公式。验证计算结果表明:新公式与计算机数值算法结果吻合较好。
Based on the concept of equivalent soil resistivity and the previously derived analytic formula for grounding resistance of a single rod in two^layer soil, an analytic formula is deduced to estimate grounding resistance of combined grounding rods in two^layer soil. The results of verifying calculation show that it agrees with the results of computer numerical arithmetic.
