等值复数镜像法在多层土壤接地计算中的应用

Application of Equivalent Complex Image Method in Multi layer Soils Grounding Calculation

介绍了等值复数镜像法。通过运用等值复数镜像法求出水平三层土壤中的格林函数，阐述等值复数镜像法的应用。编写了接地计算程序。计算结果与国内外学者的计算结果非常吻合。等值复数镜像法能使接地计算大大地简化，且能保证较高的计算精度。

This paper presents the equivalent complex image method. Through deducing the Green′s function in a three level layer soil by complex image method, application of this method is clarified. The grounding calculation software is programmed. The results are well identical with those of internal and external scholars. The grounding calculation is largely simplified with complex image method gives high precision.
