Estimation of the TBM advance rate under hard rock ...

2021-10-1  The advance rate (AR) of a tunnel boring machine (TBM) under hard rock conditions is a key parameter in the successful implementation of tunneling engineering. In this study, we improved the accuracy of prediction models by employing a hybrid model of extreme gradient boosting (XGBoost) with Bayesian optimization (BO) to model the TBM AR.

Tunnel Construction Rocks with Boring Machines -

2020-10-13  Hard Rock TBM. The hard rock TBMs use mounted disc cutters that function by fracturing the rocks and chipping them off the tunnel. The resulting muck is then moved through the cutter head openings on the machine’s conveyors, subsequently removing them from the tunnel. Two types of hard rock TBMs are the shielded or open-type machines. In the ...
