At GeoMod, we perform comprehensive numerical simulations using the finite element package ZSoil. This allows us to treat engineering problems globally and analyse geotechnical problems which are too complex for analytical solutions, taking into account physical phenomena such as time dependent soil-structure interaction. By verifying the global equilibrium of a soil-structure system, we take into account unexpected modes which are difficult or impossible to predict by analytical desk-studies. We specialize in: - tunnels, underground storage facilities, metro stations, mining - long-term predictions for soil-structure systems - earthquake engineering - shallow and pile foundation - geothermal engineering - earthwork construction and tailings - cut or fill in highways, railroads - landslides and slope stability - dams, river banks and harbours - retaining structures, water-front and excavation systems with complex excavation sequences - hydraulic structures - multi-storey buildings
