Abstract: A tunnel tunneling feasibility prediction method and system based on a TBM rock-machine parameter dynamic interaction mechanism includes: creating device information and rock mass information sample databases; analyzing and calculating a rock mass information sample database of a rising section of TBM tunneling parameters to obtain rock mass information weights under a condition of different device states; determining convergence conditions in different device information states through the rock-machine parameter dynamic interaction mechanism, and obtaining an optimal solution of tunneling parameters of a stable section of the TBM tunneling parameters under a condition of different rock mass information; and creating an optimal tunneling formula applicable to TBM tunneling through the obtained weight information and the optimal solution of the tunneling parameters of the stable section, performing TBM tunneling feasibility classification, and predicting TBM tunneling efficiency. Indexes of device parameters and rock parameters are selected based on TMB construction features.

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.
