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.
