摘　　要：为实现四层以下多层土壤水平接地网接地电阻的计算,从而满足工程设计的实际需要,利用公式法中两层土壤水平接地网接地电阻计算公式进行拓展,引入两层土壤分解法合成等效土壤电阻率,搭建计算模型.依据计算模型编制软件程序,实现多层土壤情况下水平接地网接地电阻计算.与公开发表的计算机数值计算法得值相比较,计算结果误差保持在±10%以内,验证了计算模型的有效性,软件可以使用.In order to realize the calculation of grounding resistance of multi-layer soil horizontal grounding grid under four layers and meet the actual needs of engineering design, the formula of grounding resistance of two-layer soil horizontal grounding grid is extended by the formula method, and the equivalent soil resistivity is synthesized by two-layer soil decomposition method, and the calculation model is established. According to the calculation model, a software program is compiled to calculate the grounding resistance of horizontal grounding grid in multi-layer soil. Comparing with the published values obtained by the computer numerical calculation method, the error of the calculation results is kept within ±10%, which verifies the validity of the calculation model and the software can be used.
