电剖面法同电测深法有许多相似之处。它们都是以岩石电阻率的差异为基础,都是以用四极法取得视电阻率资料推断地下地质情况为基本工作方法。这两种方法不同之处在于:电剖面法不是研究每一点上ρk值随不同的电极距的变化,而是研究用相同电极距所取得ρk值沿剖面或在整个测区中随 Electrical sectioning method with electrical sounding method has many similarities. All of them are based on the difference of rock resistivity. All of them are based on the method of obtaining the apparent resistivity data by quadrupole method to infer the underground geological conditions. The difference between these two methods is that the electrical profile method is not to study the change of ρk value with different electrode distance at every point but to study whether the ρk value obtained from the same electrode along the profile or in the whole measurement zone
