摘要
针对地铁设备接地的要求,论述地铁车站接地形式的选择和接地敷设方案的设计。在一般情况下,采用以车站主体结构钢筋为自然接地体的设计方案;在自然接地体不能满足要求时,采用设置外引人工综合接地装置、利用围护桩结构钢筋、换土、降阻剂的辅助设计方案。
According to the requirements of metro equipment grounding, metro station grounding normally adopted the grotmding scheme with the main structural reinforcement as the natural grounding body. In case the natural grounding body cannot meet the requirements, auxiliary design scheme can be adopted by making use of artificial grounding installation, reinforcement of retaining piles, changing soil structure, resistance reduction agent.
