Prediction of rock mass classification in tunnel boring machine tunneling using the principal component analysis (PCA)–gated recurrent unit (GRU) neural network
•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. |
