Analysis of the TBM monitoring data obtained during the construction of Railway Tunnels
Języki publikacji
Abstrakty
In this study, an analysis has been carried out on about 587 m of a service tunnel, excavated by a TBM in a flysch formation. Some relationships has been highlighted between the excavation specific energy, net advance rate, thrust on the cutter-head and the Rock Mass Rating. A TBM performance predictive law has been also applied verifying a scarce gap between the predicted and actual values of the net advance rate. The found relationship between excavation specific energy and RMR can help the choose of the TBM for a specific tunnel or the estimation of the net advance rate using a specific machine.
