Mechanized Tunneling

Mechanized tunneling (as opposed to conventional techniques) are all the tunneling techniques in which excavation is performed mechanically by means of teeth, picks or disks. (ITA – AITES)

Mechanized tunneling is performed with a tunnel boring machine TBM and they can bore through hard rock to soft ground.

In this section of Geotechpedia publications on mechanized tunneling can be found, covering a wide range of issues and case studies.
