Tunneling and TBM Method - p3planningengineer.com
tunnel boring machine (tbm) method There are two major shield methods around: earth pressure balanced (EPB) and slurry type shield machine. Selection of shield method depends on ground conditions, surface conditions, dimensions of the tunnel section, boring distance, tunnel alignment and construction period.

method. Trench excavation, tunnel construction and soil covering of excavated tunnels are three major integral parts of the tunnelling method. ... Bored tunnelling by using a Tunnel Boring Machine (TBM) is often used for excavating long tunnels. An
Tunnel - Wikipedia
The TBM is a multi-functional construction tool, which can excavate and remove excavated materials, and at the same time install the reinforced concrete lining of the tunnel as it progresses. This method, unlike cut and cover excavation works, does not require disruption to the road surface during construction.
