Soil-steel structures are the engineering structures that also fulfil the functions of bridges, flyovers, pedestrian bridges, culverts, tunnels, subways, farm accommodation bridges or wildlife crossings. A large group of these structures serves as municipal facilities, normally shaped as closed pipes or intended for transport purposes, e.g. for the housing of the conveyor belts. They are constructed in the form of a corrugated steel structures (steel shell) and the surrounding, specially concentrated soil. They are designed in a manner ensuring a longlasting, beneficial interaction between essential elements of the bearing system in a classic design, that is, the shell, founded on the foundation, and the soil backfill.
