METC Project Scope

METC Organisation        METC Key Personnel

 Metro C’s participation in NeTTUN will allow for testing and calibration of specific models (numerical 3D and small-scale laboratory) on site along the initial part of section T3 as follows:

  • adjustment of compensation grouting parameters in a test field placed close to the first monument that will be under-passed by the TBM
  • ground behaviour along a TBM excavated stretch of line C on a monitored ground section in green field;
  • execution of tunnels under crossing the Mura Aureliane situated in Largo Amba Aradam, first monument affected by the construction of tunnels in soft soils, with the use of compensation grouting in order to compensate settlements due to excavation and avoid impacts on the existing structure.
