The calculation results of ground potential and electric field based on relative position for vertical 3 layered-soil

The calculation results of ground potentail and electric field for vertical 3 layered-soil, the current sourec is 3000A; the depth of grounding-electrode is 4m; the width of middle soil-layered is 30001m; the resistivity of left soil-layered is 2000Ωm; the resistivity of right soil-layered is 50Ωm; the resistivity of middle soil-layered is 1000Ωm or 20Ωm; the distance between grounding-electrode and observation point maintains 3km,5km and 10km respectively when moveing on of relative position. "A" column indicated the x-coordinate of relative position in two cases, the one is that the midpoint of distance between grounding-electrode and observation point is seen as the x-coordinate of relative position, the other is that the location of grounding-electrode is seen as the x-coordinate of relative position.本数据集涵盖垂直三层土壤场景下的地电位（ground potential）与电场计算结果。本次计算的电流源为3000安（A），接地极（grounding-electrode）埋深4米，中间土层宽度为30001米；左侧土壤电阻率为2000Ω·m，右侧土壤电阻率为50Ω·m，中间土层电阻率分别采用1000Ω·m与20Ω·m两种工况。当相对位置变化时，接地极与观测点的距离分别保持为3千米、5千米与10千米。A列用于表征两种基准下的相对位置横坐标：其一以接地极与观测点间距的中点作为相对位置横坐标，其二以接地极自身所在位置作为相对位置横坐标。
