Abstract: Disclosed is an advanced detector system and method using a forward three-dimensional induced polarization method for a TBM (Tunnel Boring Machine) construction tunnel. A narrow detection space of a full-face excavated tunnel is fully used, a controller controls doors of a source and measuring electrode compartment and a shielding electrode compartment to open and controls a corresponding hydraulic delivery device to automatically and quickly arrange a source electrode system, a measuring electrode system and a shielding electrode system. Under the action of a shielding current system, tomography detection supply current is directed ahead of the working face. Three-dimensional geologic information can be obtained, and the relationship between an induced polarization half-decay time difference and a water quantity can be used to quantitatively forecast the water quantity of a water-bearing body, and meanwhile, the half-decay time difference parameter has a high capacity of distinguishing free water from bound water.

Abstract: A rock breaking seismic source and active source three-dimensional seismic combined detection system uses a tunnel boring machine for three-dimensional seismic combined detection by active seismic source and rock breaking seismic source methods. Long-distance advanced prediction and position recognition of a geological anomalous body are realized using the active source seismic method. Machine construction is adjusted and optimized according to the detection result; real-time short-distance accurate prediction of the body is realized using the cutter head rock breaking vibration having weak energy but containing a high proportion of transverse wave components as seismic sources and adopting an unconventional rock breaking seismic source seism recording and handling method. An area surrounding rock quality to be excavated is represented and assessed. A comprehensive judgment is made to the geological condition in front of the working face with the results of active source and rock breaking seismic source three-dimensional seismic advanced detection.
