摘　　要：雷电流释放主要通过接地体完成,对垂直接地体和水平接地体进行数学建模,推导两个模型的接地电阻公式,并对工程实施中接地电阻进行计算,所得结果与实测值接近。此方法具有一定工程参考价值,值得推广。Lightning current release is mainly accomplished by grounding body. The grounding body is divided into two parts of vertical grounding and horizontal grounding body. In this thesis, the math-model of the two types of the grounding grid is introduced. Grounding resistance formula is deduced through the analysis of math-model. The result of the engineering problems calculated with the combined usage of the formula is closed to the measured value. This method has certain reference value for engineering.
