PLAÇA DE LES GLÒRIES TUNNEL, BARCELONA (SPAIN, 2016)

The underground tunnel at Plaça de les Glòries (Barcelona) is constructed by a cut and cover procedure in a densely populated urban area. However, some stretches of the construction cross under four underground railway infrastructures, where conventional tunneling techniques are required.

Our experience has permitted to carry out the consultancy activities related with the geotechnical and hydrogeological design.

PRO GEO experience has helped our client in the following aspects:

  • Design of the complementary geotechnical survey and data analysis.
  • Geomechanical design and soil-structure interaction of cut and cover
  • Geotechnical modeling and design of NATM culverts (with inner umbrella).
  • 2D and 3D geomechanical modeling of the conventional tunneling under the railway underground infrastructures (box jacking alternative).

Hydrogeological design of dewatering system (3D modeling).
