Calculated parameters (soil layer resistivity, soil layer thickness, and the number of soil layers) of horizontally layered soil are usually obtained based on the measured apparent resistivity under different measurement distances, which are significant for the design, operation, and maintenance of grounding grids. Most existing calculation methods of soil parameters are just trying to make the calculation results approach the measurement data, ignoring the relationship among measurement data, the calculated soil parameters, and grounding parameters, which would increase the workload of the measurement. To better balance the distance range of the measurement data and the influence of the calculated horizontally layered soil on grounding parameters, this paper systematically studies the relationship among measured apparent soil resistivity, calculated horizontally layered soil parameters, and grounding parameters. The basic theories of apparent resistivity measurement, soil parameter calculation, and grounding parameter calculation are given, the influence of soil layer thickness on the measured apparent resistivity is studied, and the influence of the calculated soil parameters on the grounding resistance of different grounding models is analysed. Based on different scales of grounding grids, the results give a corresponding reference distance range of measured apparent soil resistivity. Therefore, this paper can help decrease the workload of soil resistivity measurement during grounding parameters analysis, which has far-reaching engineering significance.

计算出的水平分层土壤参数对接地参数的影响分析

水平分层土壤的计算参数（土层电阻率、土层厚度、土层数）通常是根据不同测量距离下测得的视电阻率得到的，这对接地网的设计、运行和维护具有重要意义. 现有的土壤参数计算方法大多只是试图使计算结果接近测量数据，忽略了测量数据、计算出的土壤参数和接地参数之间的关系，这会增加测量的工作量。为了更好地平衡测量数据的距离范围和计算出的水平分层土壤对接地参数的影响，本文系统地研究了实测土壤视电阻率、计算水平分层土壤参数和接地参数。给出了视电阻率测量、土壤参数计算、接地参数计算的基本理论，研究了土层厚度对实测视电阻率的影响，并给出了计算得到的土壤参数对不同接地模型接地电阻的影响。分析。根据不同尺度的接地网，给出了相应的实测土壤视电阻率参考距离范围。因此，本文有助于减轻接地参数分析过程中土壤电阻率测量的工作量，具有深远的工程意义。给出了土壤参数计算和接地参数计算，研究了土层厚度对实测视电阻率的影响，分析了计算得到的土壤参数对不同接地模型接地电阻的影响。根据不同尺度的接地网，给出了相应的实测土壤视电阻率参考距离范围。因此，本文有助于减轻接地参数分析过程中土壤电阻率测量的工作量，具有深远的工程意义。给出了土壤参数计算和接地参数计算，研究了土层厚度对实测视电阻率的影响，分析了计算得到的土壤参数对不同接地模型接地电阻的影响。根据不同尺度的接地网，给出了相应的实测土壤视电阻率参考距离范围。因此，本文有助于减轻接地参数分析过程中土壤电阻率测量的工作量，具有深远的工程意义。并分析了计算得到的土壤参数对不同接地模型接地电阻的影响。根据不同尺度的接地网，给出了相应的实测土壤视电阻率参考距离范围。因此，本文有助于减轻接地参数分析过程中土壤电阻率测量的工作量，具有深远的工程意义。并分析了计算得到的土壤参数对不同接地模型接地电阻的影响。根据不同尺度的接地网，给出了相应的实测土壤视电阻率参考距离范围。因此，本文有助于减轻接地参数分析过程中土壤电阻率测量的工作量，具有深远的工程意义。
