| Abstrait: |
The paper presents an innovative and cost-effective solution for the construction of tunnels of the roadway and railway types, executed with tunnel boring machines (TBMs), when the referred tunnels are executed in soft soils (e.g., alluviums), in seismic areas. This solution can also be used for the strengthening of existing tunnels, using the existing tunnel as a formwork for the execution of the interior strengthening. In this paper a description of the solution is presented, as well as its application to a specific case. |
