Abstract: Based on a brief description of the quantitative interpretation methods for "the utilization of fixed point source sounding data to draw geoelectric section" put forward by V.A. Komarof (relative intensity method, integral parameter method and differential parameter method), this paper deals emphatically with the results of computerized quantitative interpretation of apparent polarizability sounding curves obtained form theoretical calculation, digital simulation and physical simulation above spheroids, plates and composite plates (for the purpose of determining central depths, attitudes, upper interface locations and outlines of buried bodies). Exemplified by results of a field test, the paper also demonstrates the effectiveness of this method.
