摘要：

Telecommunications services have been interrupted by cutting off underground telecommunications cables installed inside ducts during road construction. In order to prevent such an accident, it is necessary to identify the location of the cables. The system detecting a burial location of the cables is introduced by measuring the maximum magnetic field distribution on the earth surface generated by signaling current flowing through the cables installed inside the ducts. However, an error occurred in the burial location of the cables, when several ducts are installed. Therefore, the magnetic field distribution depending on the duct arrangement is analyzed in order to find out the reason why error occurred, using magnetic field analysis software so that called JMAG.
