摘　　要：主要探讨了在相同土壤条件下,人工接地体在雷电流作用下的腐蚀寿命变化情况。以人工冲击电流的腐蚀试验为基础,通过引入年预计雷击次数的计算模型,建立了多年累积腐蚀深度的计算公式,进而估算人工接地体的腐蚀寿命。This work mainly focused on determining the changes in corrosion life of artificial earthing electrodes subjected to lightning current under the same soil condition.Based on the corrosion test with artificial impact current,a calculation model utilizing estimated count of lightning strikes per year was introduced.Then a formula for calculating the multi-year cumulative corrosion depth was established,thereby achieving corrosion life estimation of artificial earthing electrodes.
