摘　　要：在分析直流接地极设计过程中的设计参数的基础上,基于CDEGS软件系统,搭建了直流接地极仿真模型;考虑入地电流、跨步电压、最大允许温升等限制因素后,在同一初始条件下,设计了6个比选方案,指出直流接地极内外环半径最优比例为0.73,通过对比施工量、经济性、跨步电压、面电流、线电流密度等选出设计最优方案。Based on the analysis of design parameters in the design process of DC grounding electrode,a simulation model of DC grounding electrode is built based on CDEGS software system.Considering the restrictive factors such as ground current,step voltage and maximum allowable temperature rise,six comparison schemes are designed under the same initial condition,and the method of optimizing DC grounding electrode is proposed.The optimal design scheme is selected by comparing the construction quantity,economy,step voltage,surface current,line current density,etc.
