| Abstract: | In this paper, the principle of cross-hole resistivity CT method is introduced,and the difference of resistivity between karst cave filler and surrounding rock is considered. A geoelectric model is established by numerical simulation. The apparent resistivity response and inversion imaging are discussed. A comprehensive analysis is made with engineering examples.The examples show that the cross-hole resistivity CT method is effective in karst detection and it can guide the practical engineering. |
