摘　　要：应用矩量法得出了两层土壤中矩形混凝土内立体接地网的接地电阻数值计算方法 ,用 FORTRAN语言编制了计算程序 ,用算例与有关文献比较 ,验证了方法和程序的正确性 ,分析了电阻率及上层土壤厚度对接地电阻的影响。By use of moment method, a numerical calculation method for determining the grounding resistance of a cubical grounding net in rectangular concrete foundation surrounded by two layer soil is presented in this paper. Using FORTRAN a calculation program is developed. To verify the validity of the method and program the calculated results of examples by this method are compared with that from references and.The influence of resistivity and the depth of the upper soil layer on grounding resistance is analyzed.
