Resistivity method is widely used in shallow surface geophysics. Capacitive resistivity is one of techniques which help to extend usage of resistivity method for environmentc where galvanic coupling of electrodes is difficult, for instance, frozen ground, hard rocks and engineered structures (roads, railways and others). This technique allows fast field work without galvanic coupling electrodes. The main problem is complicated calculation of forward resistivity for simple model. In results, the limitations to the usage of the technique are not clear in theoretical and practical aspects. The authors determinate the limits of electrical properties and distances for capacity resistivity. |
