Abstract: A new combination of means and method steps is used in a method of constructing long tunnels with a lining, wherein excavation is effected with a tunnel boring machine (1) with a yielding shield mantle (4), building is effected continuously under the protection of the shield tail in a modular construction with tubbing stones of a special form complementing each other to form tubbing rings (15) while, until a new equilibrium of the rock formation is reached, occurring deformation forces are absorbed by the shield tail (4) and the tubbing rings which are yieldingly constructed to a limited degree, an outer seal of the tubes is provided and the gap between the excavation (2) and the tunnel tubes is filled with a material (22) which may be yielding to a limited extent to absorb long-time deformation forces. A tunnel construction made by the method, special forms of tubbing stones and new embodiments of drive means for the tunnel are disclosed.
