摘　　要：对于杆塔的冲击接地阻抗,提出利用电磁场和电路相结合的方法进行计算。该方法将接地体划分为多个导体分段,考虑了导体段之间互感的作用,兼顾了计算效率和计算精度。与权威的接地网计算软件CDEGS进行对比,验证了计算结果的可靠性和理论的正确性。For the impulse grounding reisistance calculation of transmission line tower, this paper proposes a method with the combination of Electromagnetic field and circuit methods. The grounding is divided into several segments, and their mutual inductance are considered according to the requirment of calculation efficiency and accuracy. Through the comparison between the results and that from the authoritative CDEGS, the theoretical correction and reliability of the proposed method are validated.
