Tunnel Lining with segmental rings behind TBMs are reinforced concrete elements and must be calculated and designed according to the standards of reinforced concrete constructions. In tunnelling, however, specific circumstances must be taken in account, which make design much more complicated: The determination of loads during ring erection, advance of the TBM, earth pressure and bedding of the articulated ring, is difficult. The ring model and the design input values must be studied carefully according to the parameters of the surrounding soil.

What is a tunnel ring?
The segments put on the rock wall are joined together in order to form a concrete ring. They have several roles within the tunnel: Finishing up the internal wall of the gallery. Ensuring that the gallery will be resilient enough faced to external pressure.
What is the purpose of tunneling?
Tunnels are used for a wide variety of purposes. They provide essential links in many highways, railroads, and urban rapid transit systems. Urban water supply and distribution, sewage collection and disposal, hydroelectric power generation, flood control, and mining require extensive tunneling.
What is a tunnel in mining?
A horizontal or inclined stone drivage for development or to connect mine workings, seams, or shafts. It may be open to the surface at one end and used for drainage, ventilation, or haulage or as a personnel egress from the mine workings.
