摘要
提出了纵向三层土壤中电流场的计算模型，并通过求解拉普拉斯方程，推导出该模型中电流场计算公式．据此，可以用边界元法计算该模型中任意方式埋设的接地网的接地电阻及空间中任意一点的电位．
A numerical model for computing the current field in a vertical three layer earth structure is presented in this paper.The formulas for current field computation are deduced via mumerical solution of Laplace equations.With the help of these formulas,we can compute earth resistance by boundary element method,no matter how the conductors may arranged.This calculating method has practical value for designing grounding grids to a large hydropower plant.
