| Abstract: | Firstly, this paper discusses two expressions of apparent resistivity of the strong vertical focusing sounding method, and puts forward a simple configuration and its measurement scheme used in practice to take the place of the method mentioned above. Then the theoretical curves of apparent resistivity ps of this method calculated by means of digital filtering are analysed in'detail, and are pointed out a phenomenon of apparent increase of layers by this method and several factors affecting both the shape of apparent resistivity ps and the current electrode spacing of the point where the value of ps reaches the minimum or maximum. Finally, the reasons that why a fixed depth of investigation doesnot exist in the strong vertical focusing sounding method are expounded. Key words: The strong vertical focusing sounding method, apparent resistivity, a fixed depth of investigation, a phenomenon of apparent increase of layers, the vertical barrier shield equipo-tential sounding method |
