摘　　要：土壤模型的准确性直接影响地表电位的计算精度,进而影响直流接地极的选址与设计。现在普遍采用的土壤模型及其修正方法均不能真实反映土壤的电性结构。为此,文中提出三维非对称分层土壤模型建模方法来模拟土壤结构,然后根据注流试验结果分别针对浅层和深层大地电阻率对模型进行修正。结果表明,修正后的土壤模型很好的拟合了注流试验结果,所采用的修正方法具有修正次数少,修正精度高的优点。The accuracy of soil model decides the calculation accuracy of the earth surface potential directly,and then affected the site selection and design of the DC ground electrode.The electrical structure of the soil can＇t be truly reflected by the soil model and the modified method commonly used.To solve this problem,a three-dimensional asymmetric stratification soil model is proposed in this paper to simulate the structure of the soil,and then the model is modified for shallow and deep earth resistivity according to the results of injection test.The results show that the modified soil model is well fitted for the injection test.What＇s more,the method has the advantages of low revision frequency and high-precision.
