Abstract: A shield-carried noncontact frequency-domain electrical real-time advanced detection system and method. Noncontact electrodes are installed on a cutter head of a shield tunneling machine, current is emitted and received using capacitance coupling, the electrodes are connected to a host via a multi-way swivel joint, measured data is inversed and interpreted in real time, and the prediction result is transmitted to a control system of the shield tunneling machine so as to provide a technical support for safety construction of the shield tunneling machine; the noncontact electrodes are installed on the shield cutter head. Real-time advanced detection of geology in front of a tunnel face can be realized in the tunneling process, so that the requirement for quick tunneling construction is met, and the efficiency of advanced geological detection of the shield tunneling machine is improved; and an electrode system is only installed on the cutter head.
