摘　　要：文中利用散射迭加方法,推导了多层土壤视在电阻率的计算公式。在此基础上结合场地测试数据,利用复镜像法和电位函数计算法对天线场区的土壤模型进行反演,获得土壤分层结构。然后从电磁理论出发,根据所得到的土壤分层模型参数,推导出甚低频大地等效电阻率的3种等效法则,并对每一种等效法则下的等效电阻率进行了推导分析。According to the theory of electromagnetic scatter and superposition, it is able to deduce the formula of multi-layers soil＇s apparent resistivity. Using the methods of complex image and potential distribution, the multi-layers soil structure can be got by inverted the antenna field＇s soil model. Based on the measured data of site test, it is easy to obtain the structure parameters. Then with these parameters, it is able to deduce and analyze three effective rules of the earth VLF effective resistivity.
