Structure Design Of Tunnels

STRUCTURE magazine | Design and Construction of Tunnels

Analysis for Existing Tunnels. Work on existing tunnels discussed in this article falls into one of three major categories, 1) lining a previously unlined tunnel, 2) partial liner removal, and 3) liner replacement. The parameters used in design and analysis will vary depending on the work being performed.

Tunnel - Wikipedia

A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal.
