Influence analysis of calculated horizontally layered soil parameters on grounding parameters

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