摘　　要：为了更精确地计算接地网的接地参数,需要采用水平多层土壤模型。运用复镜像法求得水平分层土壤中点电流源的格林函数的数值解,然后泳边界元法计算了不同土壤模型中的接地参数,与国外学者的计算结果进行了比较,结果较为吻合。To calculate the grounding parameters more accurately, it is necessary to analyze the grounding parameters in the model of horizontally stratified multi-layer earth. This paper deprives Green＇ s Function by complex image method in horizontal-layered soil structure and calculated the parameters with boundary element method. The results are identical with those from other works.
