## Tunnel Boring Machine - an overview ScienceDirect Topics

2010-08-18  Tunnel boring machines (TBMs) have extreme rates of tunneling of 15 km/year and 15 m/year and sometimes even less. The expectation of fast tunneling places great responsibility on those evaluating geology and hydrogeology along a planned tunnel route. When rock conditions are reasonably good, a TBM may be two to four times faster than the drill and blast method. The problem lies in the ...

## Noise and vibration from TBM tunnelling Tunnel boring ...

As each tunnel boring machine digs through the ground it generates vibration and noise. The level of noise and vibration depends on the ground conditions. It is not possible to completely eliminate vibration generated by the TBMs as they build the twin tunnels. The level of ground-borne noise heard in a building from tunnelling depends on the type of building and how close it is to the tunnel ...
