摘　　要：用镜像法对水平分层的无限大土壤分界面进行处理,获得二层土壤中矩形钢筋混凝土立体接地网的接地电阻的一种数值计算方法,文中给出了该方法的计算式,按照这些计算式编制了相应的计算程序.与文献[1]的结果相比较,验证了方法及程序的正确性.通过2个算例,讨论了镜像个数对计算精度的影响、混凝土电阻率对接地电阻的影响,以及土壤电阻率对接地电阻的影响.该方法具有省内存、省机时、计算精度高的特点.The image method is used to follow the treatment being in progress to infinity of level with layers soil interface, gained a two layer of resistant one kind of numerical value of ground connection reckoning that rectangle armoured concrete body ground connection covers as with a net in soil, given the calculation being method＇s turn out style in culture,worked out corresponding calculation procedure according to that these calculate style. The result of Ref[ 1 ] compares with the document,correctness having verified method and procedure. By two calculating example, the resistant effect having discussed that the impact of acoustic image number over calculation accuracy, concrete resistivity dock a field, affects as well as soil resistivity is butt to butt resistant. Owe method the characteristic having province memory, calculation accuracy highly when province machine.
