Zusammenfassung:A method and system for real-time prediction of jamming in TBM tunneling. The method includes: (1) obtaining actually measured TSP physical property parameters by applying a TSP method; (2) analyzing value ranges and change trends of the TSP physical property parameters obtained in real time; (3) establishing a TSP physical property parameter sample database of a TBM tunnel; (4) establishing a mapping relationship between TSP physical property parameters and occurrence or not of jamming; (5) establishing a mapping relationship between time sequence values of tunneling parameters and occurrence or not of jamming; and (6) forecasting a TBM jamming risk in real time, and storing reliable data into the TSP physical property parameter sample database. The method and system can effectively obtain a state of surrounding rocks in time, thereby providing real-time forecasting of TBM tunneling jamming, avoiding occurrence of accidents to some extent, and improving the TBM tunneling efficiency.
