Transportation Research Record, 2000•trid.trb.orgThe construction of tunnels under soft ground conditions has been solved by the use of
special technologies and equipment. This equipment opens new possibilities for the
enlargement of existing tunnels while maintaining traffic flow. The work can be done safely
and economically even under the most difficult soil conditions. Two new tunneling
techniques for the full-face excavation of galleries under difficult ground conditions and one
new technique for cut-and-cover tunnel excavation are described.
