Tunnels and underground constructions

GEOS’s activities in the field of underground constructions are carried out on new or rehabilitated locations – tunnels, galleries, trenches, cut and cover tunnels, shafts, underground stations, collectors and retaining structures – in all areas: roads, highways, railway lines, high-speed lines, hydraulic projects, car parks, mines, and for a wide range of clients: state, local authorities, motorway concessionaires, public institutions and private companies.

GEOS has expertise numerical modeling and geotechnical calculations. Thanks to efficient 2D and 3D software, the modeling of underground structures takes into account the complex soil constitutive models, the construction phases and the soil-structure interaction in order to optimize design.
