Research on Test Method of Grounding Resistance for Layered Soil

通过MATLAB软件对现场土壤电阻率测量数据进行拟合,可定性判断土壤结构。基于电流场原理,分析了测量水平分层土壤接地电阻的电极位置布置曲线。结合土壤的实际结构和电极位置布置曲线,提出了测量水平分层土壤接地电阻的方法。采用CDEGS软件对土壤结构进行了反演分析,获得测量区域的实际土壤结构及参数。现场试验验证了分层土壤接地电阻测试方法的可靠性。

This paper proposed that the qualitative judgment method of soil structure through MATLAB fitting for the resistivity data of field soil. The electrode arrangement position graph of measuring double horizontal soil grounding resistance was analyzed by using current field theory. Combined with the actual structure of the soil and the electrode position arrangement diagram,the measurement method of horizontal layered soil grounding resistance was proposed. The actural soil structure and parameters were obtained by using CDEGS software for soil structure analysis. The field test confirms the reliability of the measuring grounding resistance method for layered soil.
