Abstract
Electromagnetic surveying method is applied in Muroran Institute of Technology`s site for power transmission steel towers for the locating of structures buried in the ground and for the study of obstruction to the application of the method. The devices employed are the EM31 and EM38 which are portable conductivity measuring instruments manufactured by GEONICS Company. With the probeable depth in the horizontal dipole mode being approximately half that in the vertical dipole mode, depths of 0.5m, 1m, 3m, and 6m may be explored using the two instruments. In the measurement test, the devices are used to determine a reinforced concrete-made multi-purpose duct that accommodates water pipes, sewers, various electric wires, and heating pipes and is buried at a depth of 2-3m in the ground. In the measurement for a 3m-deep level, a spot high in conductivity due to the reinforced concrete is detected, and the result roughly corresponds to the lay of the duct. In the measurement for a 6m-deep level, no high-conductivity spot is found, meaning there is no such structure at this depth. Although there are some other high conductivity values recorded, they are attributed to manhole covers or steel tower bases on the ground surface. 3 refs.,
