•A neural network combining principal component analysis (PCA) and gated recurrent unit (GRU) is proposed to provide accurate prediction of rock mass classification in tunnel boring machine (TBM) tunneling. | |
•The PCA–GRU model runs in approximately 20 s, which enables quick prediction of rock mass classification in TBM tunneling. | |
•The PCA–GRU model shows stronger generalization, making it more suitable in conditions where the distribution of various rock mass classes and lithologies change in percentage. |
