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.
