摘　　要：提出了基于计算机辅助分析的变电站接地网设计方法。主要内容包括：从现场实测视在接地电阻率出发，得到多层土壤结构模型；计算出多层不均匀土壤条件下不同地网结构，包括立体地网的接地电阻；分析并设计得到更经济合理的地网；同时给出地网的电位分布。A new computer aided design and analysis method of grounding system buried in multilayer soils. Obtain the soil model via the analysis of transparent resistivity. Based on this soil structure, calculate and analyze resistance for different kinds of construction of grounding system, including grids and rods. Bring forward a more economic and reasonable design. The potential distribution also being presented.
