FIELD: building, particularly underground structures erected in difficult mining and geological conditions, namely in soft watered ground bedded under tunnel scoop and forming tunnel base.
SUBSTANCE: tunnel has composite lining including hollow metal members driven in ground and forming screen, load-bearing frames and grouting concrete. Metal members are connected one to another through interlocks. At least some of metal members have rigidity varying along length thereof and increasing in direction opposite to metal member driving direction. Metal members have constant outer diameters.
EFFECT: increased tunnel reliability and operational safety due to prevention of original ground deformation during tunnel building and operation; reduced ground settlement at base of tunnel built under motor road without traffic interruption, reduced building time, power and labor inputs, material consumption due to optimal material distribution along driven member in accordance with load distribution among member parts.
