摘　　要：以无锡地铁2号线与3号线的换乘节点靖海公园站工程为例,研究地铁换乘站点之间综合接地网的布置形式及电阻值检测和计算等,并提出接地网优化方案。研究表明,水平接地极与垂直接地极的互电阻对整个接地电阻值影响较为明显,推荐采用复合接地网计算公式,可使计算结果更为精确。实践证明,靖海公园站3号线接地网优化方案合理。By taking Jinghai Park Station on Wuxi subway Line 2 and Line 3 as the research transfer node, the layout form and detection of electrical resistance for comprehensive grounding grid at the nodes between metro transfer stations are investigated, including the electrical resistance check and calculation, an optimization scheme is proposed. The research shows that the mutual resistance between horizontal and vertical earthings has obvious influence on electrical resistance for grounding grid, so the formula of composite grounding grid is recommended to make a more accurate calculation. Practical application has proved that the optimization scheme of Line 3 at Jinghai Park Station is reasonable.
