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

Deep Underground Science and Engineering
Due to the complexity of underground engineering geology, the tunnel boring machine (TBM) usually shows poor adaptability to the surrounding rock mass, leading to machine jamming and geological hazards.

Applicability of geomechanical classifications for estimation of strength properties in Brazilian rock masses

Anais da Academia Brasileira de Ciências
Many authors have been proposed several correlation equations between geomechanical classifications and strength parameters. However, these correlation equations have been based in rock masses with different characteristics when compared to Brazilian ...

Classification and Prediction of Rock Mass Boreability Based on Daily Advancement during TBM Tunneling

Buildings
The rock classification system was initially applied to drill-and-blast tunnels and subsequently adapted for TBM tunnels; however, the majority of these systems primarily focused on rock stability while neglecting considerations of boreability.
