Three expert systems for inversion were applied into practical engineering. Basing on the formulation of apparent resistivity in whole space, the curves of time vs. response which were gotten from practical exploring were transformed into the curves of depth vs. apparent resistivity by VC program. The data which were gotten from measurement line on working face in tunnel were transformed into the section map of depth vs. apparent resistivity. The result shows that expert system for inversion is feasible.
