Tunneling Machines an overview ScienceDirect Topics

1975-1-1  As the use of TBMs and micro-tunnel boring machines (MTBM) increases with advancements in tunneling technology, contractors are more and more willing to tunnel in difficult ground conditions. As a result, there have been a number of cases of tunneling machines becoming stuck or breaking down. In order to facilitate the repair and/or “rescue” of the tunneling machines and get the projects completed,
