摘　　要：土壤电阻率高的地区建筑接地装置的接地电阻难以达到规范要求,运用等效半球体接地原理,在地铁运营控制中心接地系统设计及施工中采用电解接地极进行降低接地电阻,根据理论计算,确定电解地极使用数量,达到降阻目的,经实际测量,验证了设计的正确性。The grounding resistance of grounding devices in the area with high soil resistivity is difficult to meet the standard requirements. With the application of equivalent hemispheric body grounding principle, we adopted electrolytic grounding in the design of grounding system and construction of subway operation control center to reduce the grounding resistance. According to theoretical calculation, we determined the number of electrolytic electrode to achieve the purpose of reducing resistance.
