Abstract
As TBM construction method is widely applied to construct underground transmission lines, increasing attention has been drawn to SFRC(steel fiber reinforced concrete) segment with respect to structural characteristics. Health hazards of electromagnetic wave which the underground transmission lines emit has emerged, and there is a concern that electromagnetic wave can be amplified because a segment characteristic such as electrical conductivity is changed by steel fibers. In order to analyze correlation between steel fiber dosage and electromagnetic wave, the specimens were fabricated on three conditions to perform experimental tests. From the measured data, it is proven that there is no correlation between the electromagnetic wave and steel fiber reinforced concrete.
