Advances in Tunnel Boring Machine Technology

2020-10-19  In the past decade and a half, Malaysia’s tunnelling and underground space has experienced some impressive developments. In 1994, the first Tunnel Boring Machine (TBM) was used for the Sg. Kelinchi Transfer Tunnel (The Institution of Engineers Malaysia, 2020). From then on, Malaysia’s tunnelling has created tunnels for mega infrastructure projects,such as the Continue

Estimation of the TBM advance rate under hard rock

2020-7-6  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.
