Analysis on the relationship between layout and consumption of face cutters on hard rock tunnel boring machines (TBMs)
(Journal article; Peer reviewed, 2018)The consumption of TBM disc cutters is influenced by the ground conditions (e.g. intact rock properties, rock mass properties, etc.), the TBM boring parameters (e.g. thrust, RPM, penetration, etc.) and the cutterhead design ... -
Influence of subjectivity in geological mapping on the net penetration rate prediction for a hard rock TBM
(Journal article; Peer reviewed, 2018)The net penetration rate of hard rock tunnel boring machines (TBM) is influenced by rock mass degree of fracturing. This influence is taken into account in the NTNU prediction model by the rock mass fracturing factor (ks). ... -
Validity of the NTNU Prediction Model for D&B Tunnelling
(Peer reviewed; Journal article, 2023)The Norwegian University of Science and Technology (NTNU) has since the early 1970s published prediction models for estimated production rates, time consumption, and costs for rock works. Since the early development of the ...
