摘　　要：对阿海水电站工程接地网降阻设计与施工进行了阐述,通过新增接地网降阻设计在上游水库新增水下接地网,并在两岸埋设10套DK-AG/F防腐电解地极以降低河床土壤电阻率,降阻改造方案实施后,经测试工频接地电阻由原来的0.443Ω下降到了0.299 8Ω,满足了不大于设计值0.37Ω的要求。Grounding grid’s resistance - reducing design and construction in Ahai Hydropower Station project arenew grounding - grid - add design,underwater grounding grid has been built in the upstream reservoir anticorrosion electrolytic electrodes have been buried in both sides of the reservoir. With the power frequency earthing resistance’s measurement value decreases from the former 0. 449＋ to 0. 2998＋,whichrequirement.
