| Abstract: |
The paper presents two innovative and cost-effective concepts for the construction of tunnels using the tunnel boring machine (TBM) technique: the TISB concept to be used when the referred tunnels are executed in soft soils (e.g., alluviums), in seismic areas; and the TMF concept, which allows for the use of a single tunnel that provides the capabilities usually obtained with two parallel roadway tunnels. The paper also presents a proposal for a roadway tunnel, now under study, crossing the Tagus river, in Lisbon, in which these concepts are applied. |
