摘　　要：用矩量法,对埋在左右分层土壤中,含水平及竖直钢筋的复合接地网的接地电阻进行了研究,得出数值计算方法,并用有限大的面积来代替两种不同土壤的无限大分界面进行求解.用FORTRAN语言编制了计算程序,与文献[7]的计算公式进行比较,检验了该方法的正确性.文中给出了3个算例.With the method of moments,the two layers of buried soil in the vertical,horizontal and vertical reinforcement with composite grounding resistance of grounding grids were studied,the numerical methods is obtained.It is used with limited large area instead of two different soil infinite sub-interface to solve,the computer program is compiled,compared with the formula in Ref[7] the correctness of the method can be tested.then three examples are gived.
