对高土壤电阻率地区地铁车站综合接地网的探讨

On Comprehensive Grounding System of Metro Station in High Soil Resistivity Area

在分析地铁车站综合接地常规设计的基础上,针对高土壤电阻率地铁车站提出了双层接地网的设计方案。重点分析了双层接地网的设计特点及其在施工中的注意事项,供高土壤电阻率地区的地铁综合接地设计参考。

Based on an analysis of the conventional design of comprehensive grounding at subway station,and those built in high soil resistivity area,a double-grounding grids design is proposed in the paper.The design features of double-grounding grids and the points for attention during construction are mainly analyzed,to provide a reference for the design of comprehensive grounding at subway station located in areas of high soil resistivity.
